Revision notes and practice question for gas exchange: https://www.tes.com/teaching-resource/gas-exchange-11804216 Follow me on Instagram: https://www.instagram.com/sciencesauce_online/ Twitter: https://twitter.com/science_sauce Facebook: https://facebook.com/sciencesauceonline/ The alveoli ("many alveoli", "one alveolus") are the sites of gas exchange in the lungs. They are tiny air sacks sometimes described as being cauliflower-shaped. Oxygen diffuses across the lining of the alveoli and blood capillaries into and into red blood cells. Carbon dioxide diffuses from the blood to the alveoli. A concentration gradient is maintained by breathing as well as blood flow. The main adaptation of the gas exchange surface are: 1. Large surface area 2. Thin wall 3. Moist lining 4. Good blood supply 5. Good ventilation

What Happens When You Breathe? How The Lungs Work Animation - Respiratory System Gas Exchange  Video
 
03:05
Breathing In (Inhalation) When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs). Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin (HEE-muh-glow-bin) helps move oxygen from the air sacs to the blood. At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery. Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues. Breathing Out (Exhalation) When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity. As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth. Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs. How the Lungs and Respiratory System Work You usually don't even notice it, but twelve to twenty times per minute, day after day, you breathe -- thanks to your body's respiratory system. Your lungs expand and contract, supplying life-sustaining oxygen to your body and removing from it, a waste product called carbon dioxide. The Act of Breathing Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes. For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus. The Lungs As the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli. The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from the inhaled air passes through the alveoli walls and into the blood. After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs. As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale. The Diaphragm's Role in Breathing Inhalation and exhalation are the processes by which the body brings in oxygen and expels carbon dioxide. The breathing process is aided by a large dome-shaped muscle under the lungs called the diaphragm. When you breathe in, the diaphragm contracts downward, creating a vacuum that causes a rush of fresh air into the lungs. The opposite occurs with exhalation, where the diaphragm relaxes upwards, pushing on the lungs, allowing them to deflate. Clearing the Air The respiratory system has built-in methods to prevent harmful substances in the air from entering the lungs. Respiratory System Hairs in your nose help filter out large particles. Microscopic hairs, called cilia, are found along your air passages and move in a sweeping motion to keep the air passages clean. But if harmful substances, such as cigarette smoke, are inhaled, the cilia stop functioning properly, causing health problems like bronchitis. Mucus produced by cells in the trachea and bronchial tubes keeps air passages moist and aids in stopping dust, bacteria and viruses, allergy-causing substances, and other substances from entering the lungs. Impurities that do reach the deeper parts of the lungs can often be moved up via mucous and coughed out or swallowed. In the lungs, oxygen and carbon dioxide (a waste product of body processes) are exchanged in the tiny air sacs (alveoli) at the end of the bronchial tubes.

Lung Anatomy and Physiology | Gas Exchange in the Lungs Respiration Transport Alveoli Nursing
 
08:01
Lung anatomy and physiology of gas exchange in the lung alveoli during respiration nursing lecture. This lecture details the anatomy of the lungs and how gas exchange in the lungs takes place between carbon dioxide and oxygen. The lung is made up of many components that participant in gas exchange. Inhaled air with oxygen enters into the upper respiratory system via the nose or mouth then through the nasal cavities, larynx, and trachea which splits at the carina into the right and left bronchus (primary bronchi). The primary bronchi and pulmonary vein and artery enter into the lungs at the hilum. The pulmonary artery delivers unoxygenated blood to the lungs, and the pulmonary vein delivers oxygenated blood back to the heart. The primary bronchi branches off into the lobar bronchi (also called secondary bronchi) then into the segmental bronchi (also called tetiary bronchi), and then into even smaller areas such as the bronchioles. The bronchioles connect to the alveolar sacs via the alveolar ducts. Gas exchange occurs in the alveolar sac within the alveoli. The alveoli sacs contain capillaries that help with transporting carbon dioxide and oxygen in and out of the body. The pulmonary artery brings unoxygenated blood through the capillary and carbon dioxide transports across the thin capillary wall and is transported out of the body through exhalation. Then the inhaled oxygen transports across the capillary wall onto the red blood cells which is taken via the pulmonary vein back to the heart to replenish the body with fresh oxygenated blood. Other facts about lung anatomy: the right lung has three lobes while the left lung has two lobes. The lung is made up of two layers: visceral pleura (surrounds the lungs) and parietal pleura (attaches to the thoracic cavity). In between these layers, is a small space of fluid that allows the lungs to glide on each other during inhalation and exhalation.

Travel of Air Through Respiratory System - Gas Exchange in the Lungs - Nose to Alveoli Pathway
 
02:10
Gas Exchange - Delivery of Oxygen & Elimination of Carbon dioxide - Medical Animation Air first enters the body through the mouth or nose, quickly moves to the pharynx (throat), passes through the larynx (voice box), enters the trachea, which branches into a left and right bronchus within the lungs and further divides into smaller and smaller branches called bronchioles. The smallest bronchioles end in tiny air sacs, called alveoli, which inflate during inhalation, and deflate during exhalation. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation.

Know more about Exchange Of Gases. NEET Zoology XI Breathing and Exchange of Gases
 
08:37
Know more about Exchange Of Gases. NEET Zoology XI Breathing and Exchange of Gases Exchange of gases in human lungs and tissues: The air reaches the alveoli of the lungs during the inspiration. The atmospheric air contains: Nitrogen - 78% Oxygen - 21 % Carbon dioxide - 0.03% The interchange of gases in the lungs occurs between the blood of the blood capillaries and the air of the alveoli of the lungs. Gases have some properties which are as follows: Gases always diffuse from an area of higher concentration to the area of lower concentration. During respiration the lungs and the respiratory tract are never empty of air. Instead, there is a tidal volume of air (about 500 ml). The total pressure exerted on the walls of the alveoli by the mixture of gases is the same as atmospheric pressure, 760 mm of Hg (millimeters of mercury). Each gas in the mixture exerts a part of the total pressure proportional to its concentration which is called the partial pressure. Table : Partial Pressure of Respiratory Gases (A) Pulmonary Gas Exchange (Gas Exchange in Lungs between alveoli and deoxygenated blood) Diagrammatic representation of exchange of gases at the alveolus and the body tissues with blood and transport of oxygen and carbon dioxide (B) Gas Exchange in Tissues (between oxygenated blood and tissues) Transport of gases in Blood: Blood carries oxygen from the lungs to the heart and from the heart to various body parts. The blood also brings carbon dioxide from the body parts to the heart and then to the lungs. A. Transport of Oxygen: As dissolved gas: About 3% of oxygen in the blood is dissolved in the plasma which carries oxygen to the body cells. As oxyhaemoglobin: About 97% of oxygen is carried in combination with haemoglobin of the erythrocytes. Bohr’s Effect : The relationship between the pCO2 and the percentage saturation of Hb with O2 (or affinity of Hb for O2) is known as Bohr’s effect. increase in pCO2 decrease affinity of Hb for O2 therefore promotes dissociation of Hb(O2)4 → Hb + 4O2.Ø decrease in pCO2 increase affinity of Hb for O2 therefore stimulates association of O2. Hb+ 4O2 → Hb + 4(O2)4. A Diagram of a section of an alveolus with a pulmonary capillary For more such resources go to https://goo.gl/Eh96EY Website: https://www.learnpedia.in/

Gas Exchange in Alveoli Animation - Pathway of Air through Respiratory System Video – How Lungs Work
 
01:58
Air first enters the body through the mouth or nose, quickly moves to the pharynx (throat), passes through the larynx (voice box), enters the trachea, which branches into a left and right bronchus within the lungs and further divides into smaller and smaller branches called bronchioles. The smallest bronchioles end in tiny air sacs, called alveoli, which inflate during inhalation, and deflate during exhalation. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation. The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood averages about 1 micron (1/10,000 of a centimeter, or 0.000039 inch) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Biology of the Heart : Function of the Heart). Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide. Gas Exchange Between Alveoli and Capillaries: To support the exchange of oxygen and carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter of oxygen is transferred from the alveoli to the blood each minute, even when the person is at rest. At the same time, a similar volume of carbon dioxide moves from the blood to the alveoli and is exhaled. During exercise, it is possible to breathe in and out more than 100 liters (about 26 gallons) of air per minute and extract 3 liters (a little less than 1 gallon) of oxygen from this air per minute. The rate at which oxygen is used by the body is one measure of the rate of energy expended by the body. Breathing in and out is accomplished by respiratory muscles. Air is brought to the alveoli in small doses (called the tidal volume), by breathing in (inhalation) and out (exhalation) through the respiratory airways, a set of relatively narrow and moderately long tubes which start at the nose or mouth and end in the alveoli of the lungs in the chest. Air moves in and out through the same set of tubes, in which the flow is in one direction during inhalation, and in the opposite direction during exhalation. During each inhalation, at rest, approximately 500 ml of fresh air flows in through the nose. Its is warmed and moistened as it flows through the nose and pharynx. By the time it reaches the trachea the inhaled air's temperature is 37 °C and it is saturated with water vapor. On arrival in the alveoli it is diluted and thoroughly mixed with the approximately 2.5–3.0 liters of air that remained in the alveoli after the last exhalation. This relatively large volume of air that is semi-permanently present in the alveoli throughout the breathing cycle is known as the functional residual capacity (FRC). At the beginning of inhalation the airways are filled with unchanged alveolar air, left over from the last exhalation. This is the dead space volume, which is usually about 150 ml. It is the first air to re-enter the alveoli during inhalation. Only after the dead space air has returned to the alveoli does the remainder of the tidal volume (500 ml - 150 ml = 350 ml) enter the alveoli. The entry of such a small volume of fresh air with each inhalation, ensures that the composition of the FRC hardly changes during the breathing cycle.

Human Lungs | Parts of Respiratory system | Human anatomy | 3D animation videos

Lungs - Part of Respiratory system | Human anatomy | 3D animation videos Humans for respiration need a continuous supply of oxygen. Humans take in oxygen and leave out carbon dioxide, which is the poisonous waste product in the process of respiration. The lungs are essential respiratory organs in the human body. The human anatomy consists of two lungs. They can be called as the left and the right lung, respectively. The left lung has two lobes while the right lung has three lobes. The lungs contain approximately 1500 miles of airways and about 300 to 500 million alveoli. The total surface area is an approximate of 70m^2 (m-square) in a fully grown human body, (roughly the size of a badminton court). An alveoli , also known as "little cavity", is derived from the Latin word "alveolus", and these are the terminal ends of a respiratory tree and are shaped like a hollow-cavity. The average respiratory rates of a resting adult is about 10-20 breaths per minute. We spend about 1/3rd of a minute in inhaling. The total breathing capacity, however depends on the individual, that is, it varies on factors depending on age, height, weight and sex. It is observed that females tend to have a 20-25% lower breathing capacity than males, while tall people tend to have a larger lung capacity than shorter people. And people living in low-lined areas, that is, at the sea-level, tend to have a smaller lung capacity than those people living at a higher altitude. People who smoke have a lower lung capacity than non-smokers. Lungs function similar to that of bellows, which is a mechanical device that blows strong current of air. **Lungs convert the hormones that cause the narrowing of blood vessels and drives the blood pressure up and also remove the waste products in the blood.** A lung is measured to be between 10-12 inches long. The two lungs are separated by a structure called "media sternum". The lungs are covered by a structure known as the "pulmonary pleura". The lung is an important organ that performs various functions that happen every second of our lives, out of which breathing is considered to be the most essential. As previously mentioned, the lungs take in oxygen and give out carbon dioxide. The air that we breathe in, enters the human body and reaches to the lungs through a windpipe , called trachea, which branches further into two main tubes which distributes the air supply to both the left and the right lung , respectively. These tubes further divide themselves into 22 times the number of branches resulting in the formation of more than 100,000 smaller tubes, called bronchioles, and about 300 million air sacs( or alveoli), which are only about a 0.3 mm in diameter. Since the walls of the alveoli are 1/50th the thickness of a tissue paper and are also covered up with millions of tiny blood vessels, called capillaries, there is a free-flow exchange of both, oxygen and carbon dioxide, between the body and the environment. The lungs play an important role in the body's defense against infection and other harmful environmental factors. Air that is inhaled either through the nose or the mouth may consist of various dust particles or infectious agents, and ended up getting stored in the lungs. Mucus, which is a sticky liquid that is produced by the lungs, may trap the inhaled particles while the lung's white blood cells , that serve as protective agents, aid in the engulfment and destruction of such harmful matter and bacteria. Hence one good alternative is to cough. Coughing helps clear the mucus and other materials from the lungs.

ADDITIONAL NOTE: Breathing in allows oxygen to get in the lungs, be diffused into the blood to be transported to cells of the body for respiration. Respiration occurs and produces carbon dioxide as a waste product which needs to be removed from the blood.When we breathe out carbon dioxide can then be released. Thanks for watching!
