The document describes the anatomy and mechanism of the human respiratory system. It outlines the main organs - nose, pharynx, larynx, trachea, and lungs. It explains that the nose warms and filters air before it reaches the lungs. The lungs contain bronchi and bronchioles that facilitate the exchange of oxygen and carbon dioxide between inhaled air and blood. The document also describes the process of inspiration where intercostal muscles and the diaphragm expand the chest cavity to inhale air, and expiration where they relax to exhale air from the lungs.
1. The passage describes the function and key organs of the respiratory system.
2. It explains that the respiratory system's main function is gas exchange, taking in oxygen and removing carbon dioxide through breathing.
3. The key organs involved are the mouth, nose, trachea, lungs, bronchioles and alveoli, where oxygen diffuses from the alveoli into the blood and carbon dioxide diffuses out.
The respiratory system includes the nose, mouth, pharynx, trachea, bronchi, lungs, diaphragm, and circulatory system. Air enters through the nose or mouth, passes through the pharynx and trachea, reaches the lungs where oxygen passes to the blood in the circulatory system, and carbon dioxide is breathed out. The diaphragm and lungs work together to inhale oxygen and exhale carbon dioxide as we breathe.
The respiratory system functions to oxygenate tissues and remove carbon dioxide through gas exchange. It consists of the upper respiratory tract including the nose and pharynx, and the lower respiratory tract including the larynx, trachea, bronchi, bronchioles and alveoli in the lungs. Oxygen diffuses into the blood in the alveoli while carbon dioxide diffuses out. Breathing is controlled by respiratory centers in the brain and involves inspiration through contraction of the diaphragm and expiration through relaxation.
The respiratory system consists of organs and structures that facilitate gas exchange. It includes the lungs, airways, blood vessels, and muscles that allow breathing. 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 document discusses respiratory volumes and capacities. It defines various lung volumes including tidal volume, inspiratory reserve volume, inspiratory capacity, functional residual capacity, expiratory reserve volume, residual volume, vital capacity, and alveolar ventilation rate. It explains that tidal volume is around 500ml per breath and vital capacity is the total lung volume and is around 4800ml. The document also discusses factors that influence respiratory rate and depth such as carbon dioxide levels, oxygen levels, temperature, exercise and emotions.
The human respiratory system involves the inhaling of oxygen and exhaling of carbon dioxide. It is divided into an upper respiratory tract and lower respiratory tract. The upper tract includes the nose, nasal cavity, throat and voice box. The lower tract contains the lungs, trachea, bronchi and bronchioles. The lungs obtain oxygen and remove carbon dioxide via alveoli, while other parts like the diaphragm and ribs aid in breathing movements.

The respiratory system allows for oxygen intake and carbon dioxide elimination through the process of breathing, which consists of inspiration and expiration. The organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli. The upper respiratory tract functions to warm, moisten and filter air, while the lower respiratory tract transports air to the lungs for gas exchange to occur between the blood and alveoli.
The primary function of the respiratory system is to supply blood with oxygen and remove carbon dioxide waste from cells. The respiratory system 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, bronchioles, and into the alveoli where gas exchange occurs. Oxygen passes from the alveoli into the bloodstream and carbon dioxide passes from the bloodstream into the alveoli to be exhaled. Keeping the respiratory system healthy includes avoiding smoking, pollution, and exercising regularly.
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 human respiratory system takes in oxygen and expels carbon dioxide using the lungs and other organs. The lungs carry out the exchange of gases as we breathe. Red blood cells collect oxygen from the lungs and distribute it throughout the body. During inhalation, the diaphragm and intercostal muscles contract and expand the rib cage and lungs, increasing their volume and allowing more air to enter. Exhalation is the movement of air out of the bronchial tubes and lungs to the external environment during breathing.
The respiratory system allows for gas exchange in the body. It begins with the nostrils, where air enters and exits the nasal cavity to be warmed. The pharynx and larynx allow air to pass to the trachea and then bronchi, where air flows into the lungs. The lungs, located in the chest, have lobes and facilitate breathing, respiration, and protection from infection. Inhalation draws oxygen into the lungs through muscle contraction and exhalation removes carbon dioxide as a waste product.
The respiratory system supplies oxygen to the blood and removes carbon dioxide. It includes the lungs, which take in oxygen and release carbon dioxide, and the bronchial tubes that distribute air. During exercise, the respiratory rate and tidal volume increase to provide more oxygen to working muscles and remove their carbon dioxide waste. A trained respiratory system responds better to exercise through increased lung capacity and strength.
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 allows for breathing and the exchange of oxygen and carbon dioxide throughout the body. It is made up of the lungs, which are the main organ, as well as the nostrils, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli. Oxygen enters the body through the nostrils and is transported through the respiratory tract to the alveoli in the lungs, where it passes through membranes into the bloodstream and is circulated throughout the body by the circulatory system. The diaphragm and chest muscles help draw air in and out of the lungs during breathing.
Anatomy/Physiology Slideshow: The Respiratory SystemLHSprincipal
The respiratory system brings air into the body during breathing. It includes the nose, throat, trachea, and lungs. In the lungs, oxygen from the air is transferred to the bloodstream and distributed to cells throughout the body. The respiratory system has several parts - air enters through the nose and passes through the pharynx and larynx before reaching the trachea. The trachea divides into bronchi that lead into the lungs and branch into smaller bronchioles and alveoli, where oxygen and carbon dioxide are exchanged between the blood and air.
The respiratory system consists of the airways, lungs, and respiratory muscles that work together to oxygenate the body and remove carbon dioxide. It has two main functions: bringing oxygen into the body and removing carbon dioxide and water. The nose warms and filters air before it reaches the lungs. The pharynx connects the nose and mouth to the esophagus and helps swallow food and breathe. The larynx contains vocal cords and produces sounds when speaking or singing. The diaphragm contracts and expands the lungs to breathe in and out without conscious effort.
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 respiratory system has two main functions: to supply blood with oxygen and remove carbon dioxide. It has an upper respiratory tract that warms and filters air and a lower tract that includes the trachea and lungs. The lungs contain millions of alveoli that absorb oxygen and release carbon dioxide and have a sponge-like structure.
The human respiratory system allows for gas exchange between the external environment and tissues within the body. It consists of the respiratory tract and respiratory organs. The respiratory tract includes the nose, pharynx, larynx, trachea, bronchi and lungs. The lungs contain alveoli which facilitate the diffusion of oxygen into the bloodstream and carbon dioxide out. Breathing is controlled by the respiratory centers in the medulla and involves inspiration through muscle contraction and expiration through relaxation. Disorders can disrupt gas exchange like asthma and emphysema.
The respiratory system allows for gas exchange between the lungs and blood. It consists of the upper respiratory tract including the nose and throat, and the lower respiratory tract including the windpipe, bronchi, and lungs. Respiration involves breathing in oxygen which diffuses into blood vessels in the lungs, and breathing out carbon dioxide which is transported from tissues. The circulatory system then carries oxygen to tissues through blood vessels and removes carbon dioxide to maintain gas exchange throughout the body.
The respiratory system brings air into the lungs, exchanges oxygen and carbon dioxide between the air sacs and bloodstream, and exhales air. It includes the nasal cavity, pharynx, larynx, trachea, bronchial tubes, and lungs. The nasal cavity cleans and conditions air before it reaches the pharynx and larynx, which direct air to the trachea and lungs for gas exchange to occur in the alveoli.

This document provides information about respiratory air flow and volume measurements. It introduces spirometry for measuring respiratory variables and analyzing recordings to derive parameters like tidal volume, inspiratory reserve volume, expiratory reserve volume, residual volume, inspiratory capacity, expiratory capacity, functional residual capacity, vital capacity, and total lung capacity. It describes setup for spirometry and how to perform exercises to examine lung volumes/capacities and simulate an airway obstruction. Restrictive disorders reduce lung volume while obstructive disorders reduce airflow. Spirometry results like FEV1 and FEV1/FVC ratio can help distinguish between the two.
This document discusses lung volumes and capacities. It defines four lung volumes: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. It also defines four lung capacities that are combinations of the volumes: inspiratory capacity, vital capacity, functional residual capacity, and total lung capacity. It provides the normal values for each volume and capacity. Lung function tests measure these volumes and capacities to evaluate lung health and detect respiratory diseases. Spirometry uses a device called a spirometer to measure the volumes expired and inspired.
1. Tidal volume is the volume of air inhaled and exhaled during normal breathing and is around 500ml in adults.
2. Expiratory reserve volume is the additional air that can be forcibly exhaled after normal expiration, around 1000-1200ml.
3. Inspiratory reserve volume is the extra air that can be inspired after a normal inhalation, around 2500-3000ml.
4. Vital capacity is the maximum volume of air that can be inhaled or exhaled and is the sum of tidal volume, inspiratory reserve volume and expiratory reserve volume, around 3.8-4.5 liters.
This document discusses respiration and gas exchange in various organisms. It begins by defining respiration as the process of releasing energy from organic compounds. It then describes the differences between aerobic and anaerobic respiration. Next, it discusses external and internal respiration in humans and the roles of the lungs, skin, and circulatory system in gas exchange. The document proceeds to compare the respiratory structures and processes of amoebas, earthworms, insects, fish, frogs and humans. It concludes by explaining the transportation of oxygen and carbon dioxide in blood via hemoglobin in red blood cells.
Breathing and exchange of gases are important for Class 11 students. Breathing or Respiration, is vital for all living organisms as it facilitates the exchange of gases between the body and the environment. In humans, the respiratory system consists of various organs and structures that work together to ensure the intake of oxygen and the removal of carbon dioxide. Understanding the mechanisms of breathing and gas exchange is crucial for comprehending how organisms obtain oxygen for cellular respiration and expel waste carbon dioxide. Let's delve into the intricacies of this fundamental physiological process.

submitted by Garima Mittal
Lung volumes and capacities are measured in terms of the amount of air inhaled and exhaled during different respiratory functions. Tidal volume refers to the average 500mL of air inhaled and exhaled during normal breathing. Inspiratory reserve volume is the additional air inhaled beyond tidal volume, normally 2100-3200mL, while expiratory reserve volume is the extra 1200mL that can be forcibly exhaled. Residual volume is the small amount of air left after a forced exhalation. Spirometry uses a device to measure lung volumes and capacities and can help diagnose conditions like asthma or COPD that impact lung function.
1. Pulmonary ventilation involves 5 stages: ventilation in the lungs, gas exchange in the lungs, transport of gases by blood, gas exchange in tissues, and intracellular breathing.
2. Pulmonary ventilation specifically refers to the process of moving air into and out of the lungs and is accomplished through changes in thoracic volume caused by respiratory muscles and the elasticity of the lungs.
3. The key respiratory muscles involved in inspiration are the diaphragm and external intercostal muscles, while expiration is generally passive due to relaxation of inspiratory muscles and elastic recoil of the lungs and chest.
1. Respiratory system Anatomy and PhysiologiElon Yunus
The document discusses the human respiratory system. It describes the key components and functions of the respiratory system, including gas exchange in the lungs and transport of oxygen and carbon dioxide in the blood. Several respiratory diseases are mentioned, such as asthma, bronchitis, and lung cancer, which can result from breathing contaminated air. Cigarette smoke is highlighted as a major air pollutant that causes significant health problems.
1. Three main factors that affect pulmonary ventilation are surface tension of alveolar fluid, compliance of the lungs, and airway resistance.
2. Surface tension is reduced by surfactant, and a deficiency can cause respiratory distress syndrome. Compliance depends on lung elasticity and surface tension, and issues like edema or emphysema can reduce compliance.
3. Airway resistance is highest in small bronchioles, and conditions like asthma can increase resistance through smooth muscle constriction.

COURSE - B.pharm
SUBJECT - HUMAN ANATOMY&PHYSIOLOGY 2
TOPIC - RESPIRATORY SYSTEM
YEAR - 1st year, 2nd sem.
2. • What is Breathing ?
It is a simply intake of fresh air & removal of f
oul air from the body.
• What is respiration ?
it is defined as exchange of cases betwee
n body tissue & external environment suppli
ed of oxygen to the tissue & exchange of ca
rbon dioxide.
• Function of Respiration -
1. Transport of oxygen to the tissue & excreti
on of carbon dioxide.
3. 2. Excretion of volatile substance.
3.Regulation of body temp. Through the loss of h
eat.
4.Maintain the PH of blood.
4. • The respiratory system consist of different parts -
a. Nasal cavity - we have a pair of external nostrils openin
g out above the upper lips.
b.Pharynx - It is a portion of which is the common passage
of food & air.
c.Larynx - larynx is a cartilaginous box which helps to prod
uction of sounds & also known as sound box.
d.Trachea - it is commonly known as wind pipe.extends fro
m the larynx.
e.Bronchi - trachea is straight tube which divided at the 5th
thoracic vertebrae & form right & left primary bronchi.
f.Alveoli - each terminal bronchiole gives rise to a number
of very thin irregular walled & bag like structure called alv
eoli.
6. Respiratory volume & capacity -
1. Tidal volume(TV) - volume of air inspired or expi
red during a normal respiration. It approx 500ml
2.Inspiratory Reserve Volume(IRV) - additional a
mount of air a person can inspire by a forcible ins
piration . It approx 2500 - 3000ml.
3.Expiratory Reserve volume(ERV) - additional am
ount of air a person can expire by a forcible expira
tion. It approx 1000 - 1100ml.
4.Residual volume(RV) - volume of air remaining in
the lungs even after a forcible expiration. This ave
rage 1100 - 1200ml.
7. 5. Inspiratory capacity(IC) - Total volume of air a p
erson can inspire after a normal expiration. It total
(TV+IRV) i.e; 3500ml.
6.Expiratory capacity(EC) - total volume of air a pe
rson can expire after a normal inspiration. It is (TV
+ERV).
7.Functional residual capacity(FRC) - vol. of air tha
t will remain in the lungs after a normal expiration.
It is ERV+TV+IRV.
8.Vital capacity(VC) - the max. Vol. of air a person
can breathier after a forced expiration.
9.Total lung capacity - total vol. of air accommoda
ted in the lungs at the end of forced inspiration.
8. Disorder of Respiratory System -
• Asthma - it is difficulty in breathing causing whe
ezing due to inflammation of bronchi & bronchiol
es.
• Emphysema - it is a chronic disorder in which th
e alveolar walls are damaged due to which respir
atory surface is decreased .one of major cause f
or cigarette smoking.
