This slide presentation explores the human circulatory system. It begins by explaining why humans need a transport system, as diffusion alone is not effective over long distances. The key components of the human transport system are then introduced as the heart, blood vessels, blood, and lymphatic vessels. The structure and function of the heart is examined in depth, including the chambers and valves. Blood flow through the heart is depicted, with the major blood vessels associated with the heart named. Different blood vessel types are also distinguished.
This document describes the circulatory systems of fish and mammals. It explains that fish have a single circulation where blood passes through the heart once to be oxygenated at the gills before circulating to the body. Mammals have a double circulation where blood passes through the heart twice - to the lungs to be oxygenated and then again to the body in separate circuits. The advantages of double circulation are that it increases blood pressure and flow to tissues, which is important for large mammals and those with high metabolic rates.
The document provides an overview of the 12 human organ systems and how they work together. It discusses each system individually, including the circulatory, respiratory, muscular, skeletal, nervous, digestive, urinary, endocrine, and reproductive systems. It notes how certain systems like the circulatory and respiratory, and digestive and circulatory systems work closely together. Maintaining homeostasis through the coordinated function of organ systems is highlighted as important for the overall health of the human body.
Internal transport in animals occurs through circulatory systems. Simple organisms rely on diffusion through their gastrovascular cavities or two cell layers. More complex animals have developed muscular pumps (hearts) that circulate fluid (blood or hemolymph) through tubular vessels. Most animals have closed circulatory systems with double circulation, where blood is pumped from the heart to the lungs and then to the rest of the body. The human cardiovascular system has further evolved to include arteries, veins, and a four-chambered heart that fully separates oxygenated and deoxygenated blood.
The skeletal system document discusses the skeletal system and its functions. It provides information on important bones such as the skull, ribs, spine, and long bones. The skeletal system's main functions are support, protection of organs, muscle attachment, blood cell production, and mineral storage. Bones are made strong through calcium, vitamin D, and weight-bearing exercise. Joints allow movement and are held together by ligaments and cartilage. Muscles work with bones to create movement when stimulated. The three main types of muscle are skeletal, cardiac, and smooth muscle.

The circulatory system transports blood containing oxygen and nutrients throughout the body using blood vessels and the heart. The circulatory system consists of blood, blood vessels, and the heart. Blood is made of plasma, red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide, white blood cells protect against infection, and platelets form blood clots to stop bleeding. Arteries carry oxygenated blood from the heart while veins return deoxygenated blood to the heart. Capillaries connect arteries and veins to deliver blood to tissues. The heart is a hollow muscle with four chambers that pumps blood through the circulatory system around 60-100 times per minute, increasing during exercise to meet higher
The document discusses the major organ systems of the human body through a series of questions about each system. It covers the circulatory, excretory, nervous, digestive, respiratory, skeletal, muscular and integumentary systems. Each question prompts the reader to identify a specific organ or overall system shown in accompanying diagrams.
The document provides an overview of the human digestive system and the process of digestion. It begins by explaining the importance of the digestive system in breaking down food into nutrients that can be absorbed and used by the body. It then describes the main parts of the digestive system, including the mouth, esophagus, stomach, and small and large intestines. It details the physical and chemical digestion that occurs in each part, including the roles of enzymes from the salivary glands, stomach, pancreas and liver. The end products of digestion, such as glucose, amino acids and fatty acids, are then absorbed and used to power cellular processes.

Cambridge igcse biology ( 2016 2018) classification of living organismsMr Tarek Saad Ibrahim
This document discusses the key characteristics of living organisms and methods of biological classification. It describes the characteristics of movement, respiration, sensitivity, growth, reproduction, excretion and nutrition that define life. It also explains the concepts of classification, putting organisms into groups based on similarities, and the binomial naming system. Specific phyla and classes within the animal and plant kingdoms are outlined, along with the distinctive features of fungi, protoctista, prokaryotes, viruses and different types of plants and animals.
The document discusses the respiratory system and the process of breathing. It describes how breathing takes in oxygen and removes carbon dioxide. It lists the respiratory systems of different living things like fish, amphibians, plants and worms. It then focuses on the human respiratory system, describing how breathing in and out works through the movement of the ribs, diaphragm and lungs. It details the path air takes through the nose, windpipe, bronchi and alveoli where oxygen passes into blood vessels and carbon dioxide passes out of blood vessels and into the air sacs.
The document provides an overview of the skeletal and muscular systems. It discusses that the skeletal system includes bones, cartilage, joints, ligaments and tendons. It notes there are 206 bones in the adult human body and more in infants. The document outlines the two parts of the skeletal system, named the axial and appendicular skeletons, and describes the three types of joints. It also summarizes the components and functions of the muscular system, including the three types of muscle tissue.
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood through two circuits - the pulmonary circulation which carries blood to the lungs to receive oxygen and release carbon dioxide, and the systemic circulation which carries oxygenated blood to the rest of the body. Blood travels through arteries, capillaries, and veins, carrying oxygen, nutrients, hormones, and waste products like carbon dioxide. Maintaining a healthy diet, avoiding smoking and junk food, exercising regularly, and keeping a healthy weight can help support a good circulatory system.
1. The document discusses the process of cellular respiration which releases energy from food in living cells. It occurs in three stages: breathing, internal respiration in the blood, and cellular respiration in cells.
2. Aerobic respiration uses oxygen to fully break down glucose, generating more ATP. Anaerobic respiration occurs without oxygen, producing less ATP. It allows for short term energy needs like intense muscle activity.
3. The lungs take in oxygen and release carbon dioxide through breathing. Gases are exchanged between the alveoli and blood capillaries by diffusion down a concentration gradient.
A powerpoint designed for the South African Life Sciences syllabus for grade 11. Includes information about blood and it's transportation, the human heart, the lymph system etc. Hope it helps :)
The circulatory system uses the heart to pump blood throughout the body via blood vessels. The heart has four chambers - two upper atria and two lower ventricles - which work together to circulate blood in two loops. Valves between the chambers prevent backflow of blood. During each heartbeat, the atria contract together then the ventricles contract to pump blood out of the heart.
The circulatory system consists of the heart, blood vessels, and blood. The heart pumps blood throughout the body in two circulation loops - pulmonary circulation to the lungs and systemic circulation to the rest of the body. Blood carries oxygen, nutrients, hormones, and waste products and circulates in a double circulation through arteries, veins, and capillaries where gas and nutrient exchange occurs. The circulatory system helps transport these materials, fight infections, regulate temperature and pH, and heal injuries through clotting.
The circulatory system transports nutrients, gases, hormones, blood cells, and other substances to and from cells in the body. It consists of the heart, blood vessels, and blood. The heart pumps blood through two circuits: the pulmonary circuit, which carries deoxygenated blood to the lungs for oxygenation, and the systemic circuit, which carries oxygenated blood to the body's tissues before returning deoxygenated blood back to the heart. Blood contains red blood cells, white blood cells, platelets, and plasma. Red blood cells contain hemoglobin and carry oxygen. White blood cells are part of the immune system. Platelets help blood clotting. The circulatory system allows for gas, nutrient, and waste
The document summarizes the process of gas exchange in the human respiratory system. It describes the major organs involved, including the lungs, diaphragm, ribs, larynx, trachea, bronchi, bronchioles, and alveoli. It explains how breathing in and out works via the contraction and relaxation of the intercostal muscles and diaphragm. The roles of ciliated cells and mucus in protecting the lungs are also outlined. Finally, it provides details on the composition differences between inspired and expired air.
The circulatory system consists of the heart and blood vessels that maintain continuous blood flow around the body. The heart is a hollow, muscular organ located in the chest behind the sternum. It has four chambers - two upper atria and two lower ventricles. Blood vessels include arteries, which carry blood away from the heart; capillaries, which connect arterioles and venules; and veins, which carry blood back to the heart. There are two circulatory loops - systemic circulation provides oxygenated blood to the body through arteries and deoxygenated blood back to the heart through veins, while pulmonary circulation carries deoxygenated blood from the heart to the lungs and returns oxygenated blood to the heart.
The document summarizes the key parts and functions of the human digestive system. It describes how the digestive system breaks down complex molecules like lipids, proteins, and carbohydrates into smaller components that can be absorbed and used by the body. The main parts of the digestive system include the mouth, esophagus, stomach, small intestine, large intestine, and accessory organs like the liver and pancreas. Enzymes play an important role in digestion by breaking down molecules.
This is the first PowerPoint in the mrexham IGCSE Biology series. It is also available on iBooks.
It covers the Cells section from life processes of the Edexcel IGCSE Biology course
The circulatory system transports food, oxygen, carbon dioxide, and waste throughout the body via blood flowing through blood vessels. Blood is pumped from the heart through arteries and returns to the heart via veins, with the smallest blood vessels being capillaries. The heart has four chambers that cycle blood receiving oxygen from the lungs and pumping it out to the entire body. Unhealthy eating and lack of exercise can increase risks of heart problems like heart attacks by clogging arteries.
The document discusses the six levels of organization of the human body from smallest to largest: chemical, cellular, tissue, organ, organ system, and organism. It then provides information on the major organ systems that work together to keep animals alive, including the nutrition/digestive, circulatory, respiratory, excretory, nervous, reproductive, endocrine, muscular/skeletal, immune, and integumentary systems. Each system's specific functions are described.
The circulatory system functions to transport oxygen, nutrients, wastes and more throughout the body. It is composed of the heart, blood and blood vessels. The heart pumps blood through three main circuits - pulmonary, coronary and systemic. Blood carries oxygen, nutrients and waste via arteries, veins and capillaries. Conditions like high blood pressure can be dangerous if not managed.
The document discusses the components of a balanced diet, including carbohydrates, proteins, lipids, vitamins, minerals, water, and dietary fiber. It explains that carbohydrates should make up 45-65% of the diet and are a source of energy. Proteins should make up 10-35% and are needed for growth and cell repair. Lipids provide long-term energy storage and insulation. Vitamins and minerals are micronutrients necessary for proper bodily functions. Energy requirements vary depending on activity levels, age, and pregnancy.
The circulatory system transports nutrients, water, oxygen, and waste throughout the body using blood, blood vessels, and the heart. Oxygen-rich blood is carried from the heart to body cells via arteries and returns to the heart via veins as oxygen-poor blood. The heart pumps blood in two separate circuits - the pulmonary circulation transports blood to the lungs to receive oxygen and the systemic circulation transports oxygenated blood to all body tissues before returning to the heart.
The document discusses gas exchange in plants and animals. In plants, gas exchange occurs through roots, leaves, and stems. Roots use root hairs, while leaves and stems use stomata. In animals, gas exchange requires an internal transport system. The simplest systems use diffusion or ingestion of fluids in unicellular and small multicellular organisms. More complex animals have open circulatory systems where blood bathes cells directly, or closed circulatory systems where blood is enclosed and pumped in vessels. Closed systems are seen in earthworms, fish, amphibians using lungs and skin, and birds and mammals using lungs and a four-chamber heart to prevent blood mixing.
Here are the most common forms of abdominal trauma:
1. Blunt trauma - This is caused by blunt, non-penetrating forces applied to the abdomen, such as a kick, punch, fall, or car accident. Blunt trauma can cause bruising, bleeding, and organ damage or rupture without breaking the skin. The liver, spleen, and kidneys are most commonly injured in blunt trauma.
2. Penetrating trauma - Sharp objects like knives, bullets, or fragments can penetrate the abdominal wall and damage internal organs. Gunshot wounds and stab wounds are examples of penetrating trauma.
3. Blast injuries - Explosions can cause penetrating or blunt force trauma to the abdomen from bomb fragments or the blast wave itself

The document provides an overview of the human circulatory system. It begins with an introduction describing how circulation is important for transporting nutrients, oxygen, waste and more throughout the body. It then outlines the contents which will discuss blood and its components, the lymphatic system, the structure and function of the human heart, and double circulation. The human heart is described as a muscular organ located in the chest cavity between the lungs. It has four chambers - two upper atria and two lower ventricles, and valves that allow blood to flow in only one direction through the heart and vessels.
The circulatory system functions to transport oxygen, nutrients, hormones, and waste products throughout the body. It consists of the heart, blood vessels including arteries, capillaries and veins, and blood. The heart pumps blood through two circuits - pulmonary circulation to the lungs and systemic circulation to the rest of the body. Deoxygenated blood enters the heart's right side, is pumped to the lungs to receive oxygen, and enters the left side to be pumped through the body, where it releases oxygen and picks up carbon dioxide to be returned to the heart again.
The document discusses the circulatory system and blood transport in animals. It describes single and double circulatory systems. In a single circulation, blood travels from the heart to the gills to absorb oxygen and then to the organs before returning to the heart. In a double circulation, there are two circuits - one where blood passes from the heart to the lungs to absorb oxygen and release carbon dioxide, and another where blood passes from the heart to the organs and tissues to deliver oxygen before returning to the heart. A double circulation has evolved to create more pressure to pump blood around the system and separate oxygen-rich and oxygen-poor blood.
The document describes the circulatory system and its key components. It explains that the circulatory system consists of blood vessels, blood, and the heart. It details the three types of blood vessels - arteries, veins, and capillaries. The heart is divided into four chambers - two atria and two ventricles. Blood transports oxygen, nutrients, carbon dioxide and waste. Maintaining a healthy circulatory system requires regular exercise, a healthy diet, avoiding smoking and maintaining a healthy weight.
The document provides information about the respiratory and circulatory systems and how they work together with other organ systems. It discusses:
1) The respiratory system oversees gas exchange in the lungs and shares responsibility for transporting these gases with the cardiovascular system.
2) The circulatory system has three main functions - transporting substances around the body, controlling body temperature, and protecting the body. It is a double system with systemic and pulmonary circulations.
3) Blood carries out gas exchange and transports nutrients, hormones, oxygen, and waste products around the body in the circulatory system. It contains components like red blood cells, white blood cells, platelets, and plasma that each have important functions.
The document discusses the circulatory system in multicellular organisms. It begins by explaining that multicellular organisms need a transport system to distribute resources and remove waste throughout the body since diffusion is not efficient over large distances. The key components of the human circulatory system are then described in more detail, including the blood, blood vessels, and heart. The blood contains plasma and cellular components like red blood cells, white blood cells, and platelets. The heart pumps blood through a network of arteries, capillaries, and veins to deliver oxygen and nutrients and remove carbon dioxide and wastes.

The circulatory system transports blood around the body using the heart as a pump and a network of arteries, veins, and capillaries. Blood carries oxygen, nutrients, hormones, and waste products as it circulates. The circulatory system is closed and double in mammals, with the heart divided into four chambers to separate oxygenated and deoxygenated blood as it circulates to the lungs and body. Blood pressure is regulated by baroreceptors that provide feedback to control heart rate and blood vessel constriction.
Arteries take blood away from the heart. The walls of an artery are made up of thick muscular walls and elastic fibres. Veins carry blood towards the heart and also have valves. The capillaries link arteries and veins, and have a one cell thick wall. Blood is made up of four main things plasma, the liquid part of the blood; Red Blood Cells to carry oxygen; White Blood cells to protect the body from disease and platelets to help blood clot.

Strategies for Effective Upskilling is a presentation by Chinwendu Peace in a Your Skill Boost Masterclass organisation by the Excellence Foundation for South Sudan on 08th and 09th June 2024 from 1 PM to 3 PM on each day.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Diffusion is adequate to supply the transport needs
of single-celled organisms like Amoeba, shown in

But … diffusion is effective only over short
distances and is relatively slow!
Humans need to take in O2,
nutrients from their
surroundings, to pass out
waste, e.g., CO2, urea into
their surroundings and
transport other substances

Why do humans need a Transport System?
• The interior cells of multicellular animals, like
humans, are too far from the body surface for us
to rely on diffusion to bring oxygen and nutrients
to body cells and remove metabolic waste.
• In other words, our surface area is too small in
relation to the large volume of our body for
diffusion to be effective.

Why do humans need
a transport system?
Blood Vessels
Blood flow through the capillaries
Note that our blood does not come into direct
contact with the cells it supplies.
Interstitial fluid bathes the cells in the tissue
spaces and substances in it can enter the cells by
diffusion or by active transport; e.g. CO2 can
diffuse out of cells and into the interstitial fluid
and then into the blood in the capillaries.
So, it is the interstitial fluid that actually brings to
cells all of the needed materials and takes away
their waste products.

Types of Circulation
1. PULMONARY CIRCULATION:
The heart pumps deoxygenated blood to the
lungs via Pulmonary arteries, then oxygenated
blood returns from the lungs to the heart via
Pulmonary veins.

2. SYSTEMIC CIRCULATION:
Oxygenated blood is pumped forcefully out
of the heart into the Aorta then via other
arteries to all parts of the body.
Deoxygenated blood collected from various
cells returns to the heart via the Venae cavae
to be pumped out to the lungs for
oxygenation
3. CORONARY CIRCULATION:
The heart itself has its own supply of blood
vessels which bring nutrients and oxygen to the
cardiac muscle cells and removes waste.

The Lymphatic System
Because of its arrangement and functions, the
Lymphatic system is considered a part of the
circulatory system.

The Lymphatic system
consists of lymph
vessels, nodes and
some specific organs
such as the thymus,
tonsils and spleen.

Why do humans need

Summary
Large animals need a transport system to allow
the exchange of substances between the
environment and the cells.
The components of this system are: the heart
which acts as a double pump; the various types
of blood vessels that each carry blood in specific
directions around the body, and blood, the
transport medium in which are suspended cells,
and dissolved substances.

ACTIVITY 2: Heart structure and blood vessels
Answer questions 1 - 4 below in you notebook or in the box below.
1. Why are the left and right sides of the heart separated?
2. How is the pulmonary artery different from other arteries?
3. Do the pulmonary veins carry oxygenated or deoxygenated blood?
4. Why is the left ventricle thicker than the right ventricle?
42
1. The left and right sides of the heart are separated to prevent
oxygenated and deoxygenated blood from mixing.
2. The pulmonary artery carries deoxygenated blood while other arteries
carry oxygenated blood.
3. The pulmonary veins carry oxygenated blood from the lungs to the
heart.
4. The left ventricle is thicker than the right ventricle because it has to
contract forcefully to pump blood into the aorta to be distributed to
the body.

ACTIVITY 4: Heart rate
From what you have already learned about how your circulatory
system works and its relationships with other body systems, why
would your heart and pulse rate increase with exercise?
44
During exercise, the heart has to work/beat harder and more forcefully to
pump blood faster around the body in order to:
1.deliver oxygen to the working muscles because oxygen is
needed/involved in the respiratory activities that cause energy-release
from stored nutrients in muscles and other cells and
2.remove carbon dioxide and other cellular wastes from the muscle cells

Look at the diagram on the right.
What is the main difference
between the blood at 10 and at
6?
Type your response to the question in the box below.
Click CHECK for feedback.
The blood at 10 is being returned to the heart from the
cells of the lower body parts, so is deoxygenated and has
a high concentration of CO2 from their respiratory
activities. That blood might also have a lower
concentration of urea and nitrogenous wastes as it might
already have been filtered in the kidneys. The blood in 6
is strongly oxygenated.
