Study of respiration and circulation
In higher animals special respiratory surfaces are developed like skin, buccal cavity, gills and lungs. E.g. earthworm, spider, Rohu, frog and pigeon.
Respiratory System and Circulatory System
The respiratory system brings oxygen into the body and removes carbon dioxide. It includes the nose, pharynx, larynx, trachea, bronchi, bronchioles, and lungs. The circulatory system transports blood throughout the body using the heart, arteries, veins and capillaries. It has two circuits - pulmonary and systemic. Diseases can affect both systems like asthma, pneumonia, anemia and atherosclerosis.
The circulatory system and respiratory system news esaimen
The circulatory and respiratory systems adapt to high altitudes. The heart beats faster to transport more oxygen to tissues via increased blood flow and red blood cell count. Breathing also increases to take in and release more oxygen and carbon dioxide. When at high peaks, the stroke volume slightly decreases while other changes occur throughout the oxygen transport system. Altitude sickness can develop when the body does not quickly adjust to low oxygen pressures above 2,000m, causing symptoms like headaches and fatigue. Both men and women are equally affected by altitude sickness.

Respiratory system powerpoint
The document describes the key components and functions of the respiratory system. It explains that the respiratory system exchanges gases throughout the body, helps with breathing by giving oxygen to cells and removing carbon dioxide. It identifies the lungs as the essential organ of respiration, located inside the rib cage, and notes that the trachea (windpipe) connects the larynx to the lungs and bronchial tubes branch off from the bronchi to tiny air sacs in the lungs.
RESPIRATORY SYSTEM IN HUMANS
The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe.
In humans, the average breathing, or respiratory rate, mostly depends on age. A newborn's normal breathing rate is about 40 to 60 times each minute and may slow to 30 to 40 times per minute when the baby is sleeping. The average resting respiratory rate for adults is 12 to 16 breaths per minute, and up to 40 to 60 breaths per minute during exercise.
Respiration, Ventilation, Gas exchange
Respiration
The term respiration includes 3 separate functions:
Ventilation: -Breathing.
Gas exchange:-Between air and capillaries in the lungs. -Between systemic capillaries and tissues of the body.
02 utilization:- Cellular respiration
Respiratory Organs consist of two zones
- Conducting zone
- Respiration zone
Ventilation: is a mechanical process that moves air in and out of the lungs.
Gas exchange: gas exchanges in the lungs in the end of the bronchioles called alveoli Air filled alveoli account for most of the lung volume.
Lungs: Each is cone-shaped with anterior, lateral and posterior surfaces contacting ribs, Superior tip is apex, just deep to clavicle, and Concave inferior surface resting on diaphragm is the base.
Pleura: Around each lung is a flattened sac of serous membrane called pleura
Inspiration: move air from out to inside.
Expiration: move air from inside to outside

1st science 11 identifies the respiratory system and its major parts
The document discusses the respiratory system and its major parts. It identifies the nostrils, trachea, bronchial tubes, and lungs as the main respiratory organs. The respiratory system takes in oxygen and releases carbon dioxide and water vapor, allowing the body to unlock stored energy through respiration.
The Respiratory System (with animations)
Oxygen enters the body through breathing and travels down the trachea into the lungs. In the lungs, oxygen passes through tiny air sacs called alveoli and into the bloodstream. The oxygenated blood is then pumped by the heart to tissues throughout the body, where the oxygen is used for respiration and energy production. Carbon dioxide produced in tissues returns to the lungs via the bloodstream to be exhaled.
Made by sachin
Respiration is the process by which organisms obtain energy from food. There are two types of respiration: cellular respiration which breaks down food in cells to release energy using oxygen, and anaerobic respiration which breaks food down without oxygen. The document discusses the human respiratory system and process of breathing, noting that air enters through the nostrils and passes through the nasal cavity, windpipe, lungs located in the chest cavity surrounded by ribs, and diaphragm. It also compares the percentages of oxygen and carbon dioxide in inhaled versus exhaled air. Breathing is defined as the part of respiration where an organism inhales oxygen-rich air and exhales carbon dioxide-rich air through inhalation and exhalation.
Respiratory System - Physiology
The respiratory system has several key functions including supplying oxygen to the body and removing carbon dioxide. It consists of breathing, which has two phases - inhalation that draws air into the lungs and exhalation that forces air out. Gas exchange occurs externally between the lungs and blood and internally between blood and tissues. Regulation of respiration maintains appropriate oxygen and carbon dioxide levels in the blood by adjusting breathing to meet metabolic demand.

The respiratory system
The respiratory system is vital for survival as it allows oxygen to enter and carbon dioxide to exit the body. It includes the trachea that carries air to and from the lungs, bronchial tubes that branch out from the trachea and distribute air to small air sacs called alveoli where gas exchange occurs, and a diaphragm and vocal cords that help with breathing and voice functions.
1st science 12 describes the function of each respiratory organ
The document describes the parts and functions of the respiratory system. It discusses the upper respiratory tract including the nose, mouth and throat and their functions of warming, filtering and moistening air. It then discusses the lower respiratory tract including the lungs, bronchi, trachea and their functions of gas exchange and transporting air. It also describes how the ribs, rib cage and diaphragm protect the lungs and how the lungs are made up of bronchi, bronchioles and alveoli where gas exchange occurs through capillaries.
Breathing, Respiration and Human Respiratory System
The respiratory system provides oxygen to the body and removes carbon dioxide. It includes the nose, larynx, trachea, bronchi, bronchioles, lungs, diaphragm, and alveoli. The trachea branches into bronchi which branch further into bronchioles ending in alveoli where gas exchange occurs. Breathing is the physical process of inhaling and exhaling air through the lungs. Respiration is the chemical process where oxygen is used to break down glucose to generate energy in cells. While breathing occurs in the lungs, respiration occurs in cells. Common respiratory diseases include asthma, bronchitis, lung cancer, pneumonia, and COPD.
The human respiratory system ppt.1pptx
The human respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs, diaphragm and intercostal muscles. Air enters the lungs through the nose and mouth, and passes through the trachea into the bronchi and bronchioles before reaching the alveoli in the lungs. Oxygen and carbon dioxide are passively exchanged between the alveolar air and blood through the process of diffusion. Contraction of the diaphragm and intercostal muscles during inhalation lowers the pressure in the thoracic cavity, drawing air into the lungs. During exhalation, relaxation of these muscles increases pressure and pushes air out.
Respiratory and Circulatory Systems
The document describes the respiratory and circulatory systems. The respiratory system takes in oxygen through breathing and involves the lungs, trachea, and diaphragm. The circulatory system transports oxygen, food, and waste throughout the body using the heart, blood vessels, and blood. It moves from arteries to capillaries to veins to deliver oxygen and nutrients to cells and remove carbon dioxide. The respiratory and circulatory systems work together to oxygenate the blood and transport it to cells, and the circulatory system also interacts with the digestive system to deliver nutrients from food.
The respiratory system power point
The respiratory system allows us to breathe by taking in oxygen and removing carbon dioxide. It contains key structures like the lungs, which get filled with oxygen and remove carbon dioxide, the larynx containing vocal cords, the trachea or windpipe connecting the mouth and nose to the lungs, and alveoli in the lungs where gas exchange occurs. The diaphragm helps with breathing by moving up and down to draw air in and out of the lungs.
Respiratory system
The respiratory system is important as it allows our body to breathe in oxygen and breathe out carbon dioxide. It includes the nose, which filters and warms air, and the pharynx, which carries air into the windpipe. It also includes the larynx or voice box, which contains vocal cords that allow speaking, and the trachea or windpipe, which takes air from the vocal cords to the lungs. The bronchial tree in the lungs branches out to distribute air throughout the lungs.
Circulatory & respiratory systems
The circulatory system transports oxygen, nutrients, hormones, and other gases throughout the body via blood flowing through arteries and veins. The cardiovascular system, consisting of the heart and blood vessels, circulates blood which exchanges gases and nutrients with body tissues through capillaries. The respiratory system works with the circulatory system to oxygenate blood and remove carbon dioxide through breathing and gas exchange in the lungs.

Respiratory system
The respiratory system is the one of vital organs that involve in respiration
Play important role in the intake and exchange of O2 and CO2 .
The respiratory system performs two major tasks:
Exchanging air between the body and the outside environment known as external respiration.
Bringing O2 to the cells and removing CO2 from them referred to as internal respiration.
Parts of respiratory system
Upper respiratory tract: (outside thorax)
Nose
Nasal Cavity
Pharynx
Larynx
Nose:
Also called external nares.
Divided into two halves by the nasal septum.
Contains the paranasal sinuses where air is warmed.
Contains cilia which is responsible for filtering out foreign bodies.
Pharynx:
Common space used by both the respiratory and digestive systems. Commonly called the throat.
Start from the nasal and oral cavities and extends inferiorly near the level of the bifurcation of the larynx and esophagus.
There are 3 types:
Nasopharynx
Oropharynx
Laryngopharynx
Larynx:
Voice box is a short, cylindrical airway - ends in the trachea.
Prevents swallowed materials entering into the lower respiratory tract.
It Passes air into the lower respiratory tract.
Produces sounds.
Supported by cartilage help to held in place by ligaments and muscles.
Voice is produced by vibration of the vocal folds or vocal cords. The vocal folds are a pair of pliable shelves of tissue that stretch across the top of the trachea (windpipe). They are enclosed within the thyroid cartilage. The vocal folds, together with the muscles and cartilages that support them, are known as the larynx.
Biologically, the larynx evolved as a valve to protect the airway and lungs. Thus, it is positioned where the airway and the esophagus separate. The vocal folds open to allow breathing and close during swallowing to prevent food from entering into the lungs and during voicing.
Trachea:
A flexible tube also called windpipe.
Extends through the mediastinum and lies anterior to the esophagus and inferior to the larynx.
Cartilage rings help the trachea to remains open at all times.
Bronchus:
The two large tubes that carry air from your windpipe to your lungs.
Left and right main bronchus in each lung.
Each bronchus divided into bronchioles
Lung:
Each lung has a conical shape. Its wide, concave base rests upon the muscular diaphragm.
Its superior part called the apex
Both lungs are supported anteriorly by thoracic wall, laterally, and posteriorly by the rib cage.
Mediastinum
Left lung: divided into 2 lobes by, smaller than the right lung & cardiac notch accommodates the heart
Right lung: divided into 3 lobes by, located more superiorly in the body due to liver on right side

Respiratory system is the process of exchange gases oxygen and carbon dioxide in the lungs through the alveoli,in which oxygen inhaled and carbon dioxide exhaled.
Respiratory system
The respiratory system takes in oxygen and releases carbon dioxide in order to provide energy to living organisms. It involves the exchange of gases between organisms and their environments, and between cells and tissues. Respiration is the physiological process of gas exchange and oxidation of food to release energy. Different organisms have different respiratory organs suited to their environments, such as lungs in humans and other air-breathing animals, and gills in aquatic animals. The human respiratory system includes the nostrils, nasal cavity, pharynx, larynx, trachea, bronchi, and lungs, which work together to inhale oxygen and exhale carbon dioxide.
Biology Repsiration tenth class ppt
The respiratory system allows the body to breathe and exchange oxygen and carbon dioxide. It includes the nose, mouth, throat, trachea, bronchi, and lungs. The lungs obtain oxygen from inhaled air and release carbon dioxide, and the trachea and bronchi form a passageway to distribute air to and from the lungs. During breathing, the diaphragm and rib cage work to inhale air down the trachea and into the lungs' alveoli where gas exchange with blood occurs through diffusion.
Heart and Circulatory System (2).pptx
This document provides information about oxygenation, the respiratory system, and the heart and circulatory system. It discusses oxygenation in the human body through internal and external respiration. It outlines four factors that affect oxygenation: physiological, developmental, lifestyle, and environmental. It describes the 10 parts of the respiratory system and explains the functions of the respiratory system, including gas exchange, homeostasis, and speech production. It defines the circulatory system and describes the heart, including its four chambers and four valves. It explains the circulation of blood through the heart and circulatory system.
The respiratory system
The respiratory system allows for oxygen to enter the body and carbon dioxide to exit through a series of major organs. Air enters through the nose or mouth and passes through the pharynx, larynx, trachea, bronchi and into the lungs where gas exchange occurs in the alveoli. Oxygen then passes into the bloodstream and carbon dioxide passes out of the bloodstream and is exhaled. Breathing is facilitated by the contraction and relaxation of the diaphragm and rib cage which expands and contracts the chest cavity to inhale and exhale air.
Design of artificial respiratory model
Design of Artificial Respiratory Model.. Know about the respiratory system.
The respiratory system consists of the upper respiratory tract (nasal passages), the airway conduction system (larynx, trachea, bronchi, bronchioles and terminal bronchioles), and the lower respiratory tract (alveolar ducts and alveoli). Not all segments of the respiratory system mature at the same pace. The olfactory epithelium matures earliest by PND 7. The lung, however, is not considered mature until PND 21, when alveolarization and microvascular maturation are complete. This chapter will discuss the embryological development (briefly), adult histomorphology, and postnatal histologic development of each major component of the respiratory system.
Respiratory System.pptx
The document discusses the anatomy and physiology of the respiratory system. It describes the key components including the oral and nasal cavities, trachea, bronchi, bronchioles, and alveoli. It explains that the respiratory system brings oxygen into the body and removes carbon dioxide. The lungs are the primary organs and have lobes. Breathing is driven by the diaphragm and intercostal muscles contracting and relaxing to inhale and exhale air.
EVFQLeOYfTDgnNQm679.pptx
The respiratory system allows for the intake and exchange of oxygen and carbon dioxide throughout the body. It consists of the nose, pharynx, larynx, trachea, bronchi and lungs. The lungs contain alveoli where gas exchange takes place between inhaled air and blood in capillaries. During inhalation, contraction of the diaphragm and expansion of the rib cage lower pressure in the chest cavity, drawing air into the lungs. Exhalation occurs passively as the diaphragm and rib cage relax, raising pressure and pushing air out.
respiratory%20system.pptx
The respiratory system allows for the intake of oxygen and removal of carbon dioxide through a series of organs. Air enters the nose or mouth and passes through the pharynx, larynx, trachea and bronchi into tiny air sacs in the lungs called alveoli. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes out of the bloodstream and into the air that is then exhaled. Breathing is facilitated by the contraction and relaxation of the diaphragm and rib cage which expands and contracts the lungs and chest cavity, drawing air in during inhalation and pushing it out during exhalation.
The Respiratory System
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

The respiratory system allows for the intake of oxygen and removal of carbon dioxide through a series of organs. Air enters the nose and mouth, then passes through the pharynx, larynx, trachea, bronchi and into air sacs called alveoli in the lungs. In the alveoli, oxygen passes into blood vessels and carbon dioxide passes out of blood vessels, allowing for gas exchange. Breathing is driven by the contraction and relaxation of the diaphragm and rib cage, inhaling air into the lungs and exhaling air out.
Respiratory and circulatory systems.pptx
The respiratory system takes oxygen from the air into the lungs and removes carbon dioxide from the body. The circulatory system transports oxygen and nutrients throughout the body and removes carbon dioxide. When breathing in, the diaphragm contracts and lungs expand to take in air through the nose, mouth, throat and windpipe into small air sacs in the lungs called alveoli. When breathing out, the diaphragm and chest relax, pushing carbon dioxide out through the same pathways. The heart pumps oxygen-rich blood to the body and oxygen-poor blood to the lungs through networks of arteries, veins and capillaries to exchange gases and nutrients with tissues.
Structure of the Heart and Respiratory System
It is about Structure of the Heart with Types Of Circulation, Respiratory System with function of respiratory system and also Mechanism Of Respiration
Respiratory system
The document provides an overview of the respiratory system and control of respiration. It describes the key organs involved, including the nose, pharynx, larynx, trachea, bronchi, lungs and alveoli. It explains the mechanics of breathing through inspiration and expiration. Gas exchange occurs as oxygen passes from the alveoli into the blood and carbon dioxide passes from the blood into the alveoli to be exhaled. The lungs, diaphragm, ribs and autonomic nervous system work together to regulate breathing and ventilation.
Ana-physi 8.pptx
The respiratory system has the primary functions of gas exchange, filtration of air, and production of sound. It consists of the upper respiratory tract including the nose and pharynx, and the lower respiratory tract including the larynx, trachea, and lungs. Oxygen is transported to tissues via hemoglobin in the blood while carbon dioxide is transported and eliminated from the body in dissolved, carbamino, and bicarbonate forms. Chemoreceptors monitor oxygen, carbon dioxide, and hydrogen ion levels to regulate breathing via the respiratory center.
CCON Respiratory system
The document summarizes key parts of the respiratory system, including:
- The respiratory system takes in oxygen and expels carbon dioxide using organs like the lungs, trachea, and bronchi.
- The trachea is a tube that connects the larynx to the lungs, branching into the right and left primary bronchi.
- The bronchi are extensions of the windpipe that transport air to and from the lungs for gas exchange. They branch into smaller secondary and tertiary bronchi.
14.3 lecture 2019
The respiratory system has three main functions: (1) to provide oxygen to cells, (2) to remove carbon dioxide from cells, and (3) to remove water from cells. Air passes through the nose, pharynx, trachea, bronchi, and into tiny sacs called alveoli in the lungs where gas exchange occurs between the blood and air. The diaphragm and rib muscles expand the chest during inhalation, allowing air to rush into the lungs due to the created vacuum. During exhalation, the muscles relax and the chest contracts, pushing air back out.
Human respiration
Human respiration involves two main processes: [1] External respiration which is the exchange of gases between the lungs and blood, and [2] Internal respiration which is the exchange of gases between blood and tissues at the cellular level. The ultimate goal of respiration is to release energy through cellular respiration in which oxygen is used to oxidize nutrients to produce carbon dioxide, water, and ATP as energy is stored.
CCON Respiratory system
The document discusses the structure and function of the human respiratory system. It describes the major parts as the airway, lungs, and respiratory muscles. The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. The trachea is a tube that connects the larynx to the lungs. It branches within the lungs into the right and left primary bronchi. The bronchi further divide into smaller secondary and tertiary bronchi, and bronchioles which do not participate in gas exchange.

Prehistory is divided into the Paleolithic and Neolithic periods. During the Paleolithic, humans were nomadic hunter-gatherers who lived in caves and made tools from stone, bone, and wood to hunt and dress in animal skins. In the Neolithic, humans became sedentary, engaging in farming and creating pottery and fabrics. Historians study important past events using various historical sources like oral traditions, written documents, images, and artifacts to understand prehistory and how human life changed over time.
Unit 13
Spain is a democratic state divided into municipalities, provinces, and 17 autonomous communities. As a member of the European Union, Spain is an economic and political association of 27 European countries. Each autonomous community in Spain divides further into provinces, with Spain containing a total of 50 provinces. In turn, each province contains multiple municipalities. Spain has a parliamentary constitutional monarchy form of national government that separates power among the legislative, executive, and judicial branches. Autonomous communities and cities also have their own regional governments that include a parliament or assembly, government, and court of justice.
Unit 12
The document discusses population trends in Spain. It explains that a population changes due to birth rates, death rates, immigration and emigration. Spain's population has increased significantly due to decreasing death rates and increasing immigration. Population density is calculated by dividing the number of inhabitants by the area's size in square kilometers. Currently, Spain has a population density of 90 inhabitants per square kilometer.
Unit 11
Weather refers to atmospheric conditions over a short period of time, while climate describes conditions over longer periods like years. Climate is influenced by proximity to the equator, altitude above sea level, and nearness to oceans. Spain has several types of climates including Atlantic, Continental, Mediterranean, Continental-Mediterranean, and Mountain climates due to these geographic factors.
Unit 10
The document discusses water on Earth and the hydrography of Spain. Most fresh water is found as ice, in lakes, rivers or underground. Salt water is found in oceans and seas. The movement of water between the Earth and atmosphere is known as the water cycle. Spain has three drainage basins - the Cantabrian basin contains short rivers with abundant water flow, while the Atlantic and Mediterranean basins contain longer rivers with less variable flow. The Canary and Balearic Islands do not have permanent rivers, as water runs across the surface in torrents.
Unit 9
Spanish relief is very mountainous, with coastal areas generally featuring straight cliffs. The most important features are the Meseta central plateau and surrounding mountain ranges, as well as exterior mountains and the Guadalquivir and Ebro Basins. The coastal relief is divided into five regions with varying characteristics. The Balearic and Canary Islands have mountainous terrain and varied coastlines, while Ceuta is hilly and Melilla is flat. A map is a graphic representation of an area that shows it from above and to scale, using colors, symbols, and text to provide information.
Unit 8
Energy comes in different forms like light, heat, mechanical, electrical, chemical, and nuclear. There is a transformation of energy when one form changes into another. Energy sources are natural resources that provide the energy we use, and can be renewable or non-renewable. Non-renewable sources like fossil fuels and radioactive substances are exhausted because they cannot renew themselves, while renewable sources such as the sun, wind, moving water and biomass cannot be exhausted because they renew continually.
Unit 7
All matter has two fundamental properties: volume and mass. Matter can exist in three states - solid, liquid, or gas. Heat causes changes in the state of matter through melting, solidification, evaporation, or condensation as matter is heated or cooled. The use of different materials can cause environmental problems, but these can be avoided by reducing consumption, reusing materials, and recycling.
Unit 6
Our solar system is formed of the Sun and objects like planets and asteroids that move around it. The Earth, a spherical planet with three layers including the geosphere and atmosphere, rotates on its axis and orbits the Sun. The Moon is the Earth's only natural satellite, and its phases and gravitational pull cause lunar eclipses and ocean tides.
Unit 5
This document discusses the human interaction systems. It describes the main parts as the sense organs that detect stimuli and send nerve impulses to the nervous system, which interprets them as sensations. The nervous system has two parts, the central nervous system consisting of the brain and spinal cord, and the peripheral nervous system consisting of nerves. The central nervous system sends orders through nerves to effectors, which realize responses like movement. The locomotor system, consisting of muscles, tendons, bones and joints, allows us to move thanks to our skeleton.
Unit 3
The document discusses digestion, the digestive system, feeding and nutrition. It defines digestion as the process where the digestive system breaks down food to obtain nutrients, which are then absorbed in the small intestine, while waste is excreted. It explains that feeding is taking in food, and nutrition involves extracting nutrients from food and oxygen from air, distributing them through the body, and excreting waste. The document categorizes nutrients as proteins, carbohydrates, fats, minerals and vitamins, and notes that carbohydrates and fats provide energy while vitamins and minerals promote health and proteins support growth and vital functions. It emphasizes the importance of a balanced diet containing all nutrients in proper amounts.
Unit 2
Animals are multicellular organisms that feed on other living things as consumers. They have digestive systems made up of organs like the stomach and intestines to take in and digest food. Animals also have systems to take in oxygen, distribute substances throughout the body, and excrete waste residues. They interact with their environment through sense organs that detect stimuli and a nervous system that processes this information and sends instructions to effectors to execute a response.
Unit 1
This document provides an overview of living things, specifically plants. It explains that all living things are made of cells and have three vital functions: nutrition, interaction, and reproduction. It describes the structure of living things from single-celled organisms to multicellular organisms made of tissues, organs, and systems. The document defines plants as multicellular organisms that produce their own food through photosynthesis, do not move but react to changes, and most reproduce using flowers and seeds. It also outlines plants' nutrition process of absorbing water, minerals, carbon dioxide and making carbohydrates using sunlight.
Unit 15
This document provides an overview of science in the ancient world and middle ages. It describes the important early civilizations that appeared including Mesopotamia, Egypt, Greece, and Rome. Life during the middle ages is characterized by Germanic invasions, the rise of feudalism, and people abandoning cities to settle as serfs in the countryside until cities began growing again in the 13th century. Vocabulary terms related to civilization, laws, political systems, and social hierarchies of the time are also defined.

Unit 4
- 2. • Breathing and the respiratory system Breathing is part of the nutrition function. By breathing we obtein the oxygen our cells need to work. We also excrete the carbon dioxide our cells produce as a residue. We breathe with our respiratory system, which includes the airways (nasal passages, the pharynx, the larynx, the trachea, and the bronchial tubes) and the lungs. Breathing has two phases: inhalation and exhalation.
- 3. • The respirtory system
- 4. • The circulatory system The circulatory system is formed of the blood vessels and the heart. In transports nutrients, oxygen and residues around the body in the blood.
- 5. • The circulatory system
- 6. • Blood Blood is a red liquid composed of: plasma and blood cells. The most important functions of blood are: • Transport nutriens and oxygen to the cells and take away the residues to where they are excreted. • Defend our body from infections.
