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
Pleura:
The outer surface of each lung covered by a layer called pleura.
The outer - parietal pleura & the internal - visceral pleura.
The main organs of the respiratory system include the nose, mouth, larynx, pharynx, lungs, and diaphragm. The nose and mouth allow air to enter the body and pass through the pharynx into the lungs. The larynx, or voice box, is located below the pharynx and produces sound. Within the lungs, air passes through branching tubes called bronchi and bronchioles ending in alveoli where oxygen and carbon dioxide are exchanged with the blood. The diaphragm contracts and relaxes to help draw air in and out of the lungs during breathing.
The respiratory system includes the lungs, airways, blood vessels, and muscles that work together to oxygenate the blood and remove carbon dioxide. Air is brought through the nose, pharynx, larynx, trachea, and bronchi into the lungs. In the lungs, oxygen passes into blood vessels and carbon dioxide moves out. The diaphragm and ribs help breathing movements. The trachea branches into the bronchi at the carina, separating into left and right pathways to each lung lobe.
The respiratory system brings oxygen into the body and removes carbon dioxide through a series of organs including the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. Air enters the nose and mouth, and is transported through the respiratory tract to the alveoli where gas exchange occurs through diffusion. The diaphragm and rib muscles work together to inhale and exhale air during breathing.

The respiratory system is responsible for supplying oxygen to the blood and removing carbon dioxide waste. It includes the nasal cavity, mouth, pharynx, trachea, lungs, bronchi, bronchioles, alveoli, and capillaries. Air enters through the nose or mouth and travels through the pharynx, trachea, bronchi, and bronchioles before reaching the alveoli in the lungs. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes from the bloodstream to be exhaled. The blood then carries oxygen to cells throughout the body and brings carbon dioxide back to the lungs to be released. Maintaining a healthy respiratory system requires avoiding smoking and pollution, exercising,
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.
Here are the answers to your questions:
1. The sinuses are the frontal (the lower forehead), maxillary (cheekbones), ethmoid (beside the upper nose), and sphenoid (behind the nose).
2. The human respiratory system consists of the nose, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and lungs.
3. The nasal cartilages are small, elastic cartilages extending laterally from the nasal bridge that help keep the nostrils open.

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.

Functions of respiratory system.
The respiratory system has three main functions: gas exchange, regulating blood pH, and producing sounds. It consists of the upper respiratory tract including the nose and pharynx, and the lower tract including the lungs. Respiration has three steps: pulmonary ventilation, external respiration of gas exchange in the lungs, and internal respiration of gas exchange in tissues. The lungs obtain oxygen and expel carbon dioxide through breathing which involves the muscles and elastic recoil of the lungs and chest wall. The document then discusses various respiratory structures, processes, and disorders in more detail.
The respiratory system has two main stages: breathing and cellular respiration. Breathing involves inhaling air into the lungs and exhaling carbon dioxide. Cellular respiration converts glucose into ATP in cells. The respiratory system can be divided into upper and lower parts. The upper parts include the nostrils, pharynx, larynx, and epiglottis. The lower parts include the trachea, bronchi, bronchioles, lungs, diaphragm, and alveoli.
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.
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.
1. The respiratory system includes the nose, pharynx, larynx, trachea, bronchi, lungs, and associated structures. The lungs are paired organs located in the thoracic cavity.
2. Breathing is regulated by respiratory centers in the brain and chemical receptors. During inhalation, muscles contract to increase the chest cavity and draw air into the lungs. Oxygen then diffuses into blood and tissues while carbon dioxide diffuses out.
3. Lung volumes include tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume, and vital capacity. Together they describe the lungs' capacity to inhale and exhale air.
The respiratory system consists of organs and structures involved in gas exchange. Its main functions are to provide oxygen to cells and remove carbon dioxide. Key organs include the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, diaphragm and lungs. Gas exchange occurs in alveoli surrounded by capillaries. Chronic obstructive pulmonary disease and asthma are conditions where airflow from the lungs is obstructed, causing symptoms like breathing difficulty, coughing and wheezing.
The respiratory system is responsible for gas exchange between the atmosphere and body cells. It includes the nose, pharynx, larynx, trachea, bronchi, and lungs. In the lungs, oxygen passes from the air into the blood in alveoli and carbon dioxide passes from the blood into the air. The respiratory system also warms, humidifies, and filters the air brought into the body.
The document provides information on the respiratory system, including:
1. It describes the major organs of the respiratory system including the nose, pharynx, larynx, trachea, bronchi, and lungs.
2. It explains the processes of external respiration which is the exchange of gases between the lungs and blood, and internal respiration which is the exchange of gases between the blood and cells.
3. It provides details on pulmonary ventilation, the transport of oxygen and carbon dioxide in the blood and tissues, and the role of the respiratory system in regulating blood pH, sound production, thermoregulation and protection from pathogens.
The respiratory system includes the nose, trachea, lungs, diaphragm, and intercostal muscles. It allows for the intake of oxygen and removal of carbon dioxide through a process of gas exchange that occurs in the alveoli of the lungs. During inhalation, oxygen from the air diffuses into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the alveoli. This oxygenated blood is then circulated throughout the body where energy is produced through cellular respiration, and carbon dioxide is produced as a waste product.
The document summarizes key concepts about the respiratory, circulatory, and excretory systems. It explains that breathing allows us to obtain oxygen and excrete carbon dioxide through the respiratory system, including the airways and lungs. It also describes how the circulatory system transports nutrients, oxygen, and waste throughout the body via blood vessels and heart. Blood is composed of plasma and blood cells and its main functions are to transport nutrients/oxygen and defend the body from infection.
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.
The respiratory system has both primary and secondary functions. Its primary functions are to provide oxygen for metabolism and remove carbon dioxide. Its secondary functions include facilitating smell, producing speech, and maintaining acid-base balance and body water levels. The respiratory system includes the upper respiratory tract (nose, nasal passages, pharynx, and larynx) and lower respiratory tract (trachea, bronchi, bronchioles, and lungs). The lungs are located in the thoracic cavity and are surrounded by pleura. Oxygen and carbon dioxide are exchanged between air, blood, and tissues in tiny sacs called alveoli located in the lungs.
The respiratory system supplies oxygen to the body through the nose, windpipe, lungs and diaphragm. The circulatory system then transports this oxygen to cells through blood vessels and the heart. The heart has four chambers that collect and pump blood to the lungs and throughout the body in one direction via valves. It works with the respiratory system to oxygenate cells and remove carbon dioxide through repeated breathing and blood circulation.
The document discusses the process of respiration and the parts of the respiratory system. Respiration involves inhalation, which transports air into the lungs through the nose, mouth, and trachea.

The respiratory tract includes the nostrils, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. Oxygen is inhaled into the lungs and transported via blood to cells, where it is used to produce energy. Carbon dioxide is produced as a waste product and diffused from cells and blood into the lungs to be exhaled out. The respiratory system thus oxygenates the body and removes carbon dioxide through a process of ventilation and gas exchange.
The respiratory system can be divided into the upper and lower respiratory systems. The upper system includes the nose, pharynx and larynx, while the lower system includes the trachea, bronchi and lungs. Air enters through the nose, passes through the pharynx and larynx, then travels down the trachea and branches of bronchi to the lungs. In the lungs, bronchioles divide into terminal bronchioles and alveoli where gas exchange occurs by diffusion across the thin respiratory membrane. The process of breathing is controlled by respiratory centers in the brain and involves the coordinated contraction of muscles like the diaphragm.

2. Objectives
• At the end of the presentation student will be
able to:
• Introduction of respiratory system.
• Describe the anatomy and physiology of
respiratory system.
• Define upper and lower respiratory tract.
• Inlist the organs of respiratory system.
• Functions of the respiratory system.
3. Anatomy of the Respiratory
System
Respiration
Respiration is the act of breathing:
Inhaling. The act of breathing in oxygen.
Exhaling. The act of breathing out carbon
dioxide.
4. Respiratory system
• Your respiratory system is the network of organs and tissues that
help you breathe. This system helps your body absorb oxygen from
the air so your organs can work. It also cleans waste gases, such as
carbon dioxide, from your blood.
• The respiratory system is made up of the organs included in the
exchange of oxygen and carbon dioxide.
• These are the parts:
• Nose
• Mouth
• Throat (pharynx)
• Voice box (larynx)
• Windpipe (trachea)
• Large airways (bronchi)
• Small airways (bronchioles)
• Lungs
5. • Mouth and nose: Openings that pull air from outside
your body into your respiratory system.
• Sinuses: Hollow areas between the bones in your head
that help regulate the temperature and humidity of the
air you inhale.
• Pharynx (throat): Tube that delivers air from your
mouth and nose to the trachea (windpipe).
• Trachea: Passage connecting your throat and lungs.
• Bronchial tubes: Tubes at the bottom of your windpipe
that connect into each lung.
• Lungs: Two organs that remove oxygen from the air
and pass it into your blood.
6. The upper respiratory tract is made up of the:
• Nose or nostrils,
• Nasal cavity,
• Throat (pharynx),
and voice box (larynx).
7. The lower respiratory tract is made up of the:
• Trachea,
• Bronchi
• Bronchioles,
• Alveoli,
8. Lungs
• The lungs are a pair of cone-shaped organs made
up of spongy, pinkish-gray tissue. They take up
most of the space in the chest (thorax).
The lungs are surrounded by a membrane
(pleura).
• The lungs take in oxygen. Your body's cells need
oxygen to live and carry out their normal
functions. The lungs also get rid of carbon
dioxide, a waste product of the cells.
9. • The lungs are separated from each other by
the mediastinum, an area that contains the:
• Heart and its large vessels
• Trachea
• Esophagus
• Thymus gland
• Lymph nodes
10. • The right lung has 3 sections, called lobes. The
left lung has 2 lobes. When you breathe in:
• Air enters your body through your nose or
mouth.
• Air then travels down the throat through the
larynx and trachea.
• Air goes into the lungs through tubes called
main-stem bronchi.
11. • One main-stem bronchus leads to the right
lung and one to the left lung:
• In the lungs, the main-stem bronchi divide
into smaller bronchi.
• The smaller bronchi divide into even smaller
tubes (bronchioles).
• Bronchioles end in tiny air sacs (alveoli) where
the exchange of oxygen and carbon dioxide
occurs.
• You then breathe out carbon dioxide.
12. Function of respiratory system
• Allows you to talk and to smell.
• Warms air to match your body temperature and
moisturizes it to the humidity level your body needs.
• Delivers oxygen to the cells in your body.
• Removes waste gases, including carbon dioxide, from
the body when you exhale.
• Protects your airways from harmful substances and
irritants.
