Alveoli: Gas Exchange
 
03:25
Website: http://Sciencesauceonline.com Twitter: https://twitter.com/science_sauce Facebook: https://facebook.com/sciencesauceonline/ Instagram: https://www.instagram.com/sciencesauce_online/ 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

Can a paper bag really help you when you are hyperventilating? It turns out that it can. In part 2 of our look at your respiratory system Hank explains how your blood cells exchange oxygen and CO2 to maintain homeostasis. We'll dive into partial pressure gradients, and how they, along with changes in blood temperature, acidity, and CO2 concentrations, change how hemoglobin binds to gases in your blood.

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/

Follow us at: https://plus.google.com/+tutorvista/ Check us out at http://www.tutorvista.com/content/biology/biology-ii/respiration/huan-beings-gaseous-exchange.php Gas Exchange Respiratory System Breathing consists of two phases, inspiration and expiration. During inspiration, the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic (chest) cavity, and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below atmospheric pressure. Because air always flows from a region of high pressure to a region of lower pressure, it rushes in through the respiratory tract and into the alveoli. This is called negative pressure breathing, changing the pressure inside thelunsg relative to the pressure of the outside atmosphere. In contrast to inspiration, during expiration the diaphragm and intercostal muscles relax. This returns the thoracic cavity to it's original volume, increasing the air pressure in the lungs, and forcing the air out. Please like our facebook page http://www.facebook.com/tutorvista

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.

Gas exchange in different animals | Biology for All | FuseSchool
 
02:54
Respiration is carried out by all living things. Animals need oxygen to carry out aerobic respiration and they need to get rid of the waste product called carbon dioxide. This is called gas exchange. Swapping one gas for another. Animals have evolved different mechanisms for carrying out gaseous exchange. The most important thing is to create a large surface area, the bigger the surface area the faster diffusion of the gases can occur. Secondly they all have a good blood supply. You want to get oxygen into the blood and carbon dioxide out as quickly as possible so the blood travels very close to the exchange surface to once again maximise diffusion.

Respiratory System - Introduction | Biology for All | FuseSchool
 
03:08
Your respiratory system is a system in humans that is designed to extract oxygen from the air so we can use it in respiration around the body and at the same time get rid of carbon dioxide gas into the air which is the waste product from respiration. oxygen gas travels through the respiratory system, as you inhale, the molecule is drawn in through the mouth or the nose, it goes into the back of the throat where it enters a tube called the trachea. The tractor or windpipe has special rings of cartilage to keep it open at all times so you can breathe if you are lying down asleep or on a trampoline. The oxygen molecule now travels down the trachea and they will go into either the left or the right lung via a tube called the bronchus. This bronchus then splits into smaller tubes called bronchioles and finally the oxygen molecule will make its way into a tiny air sac called an alveolar, these alveoli are surrounded by tiny blood vessels called capillaries and the oxygen molecule now passes across from the air into the blood via a process of diffusion. At the same time the carbon dioxide molecule goes the other way coming out of the blood and into the alveoli as you exhale. As you exhale the carbon dioxide will take the journey back up the bronchioles a bronchus the trachea and out of the mouth. This happens to millions of molecules with each breath have about 300 million alveoli in each lung. On average, you breathe like this 12 to 16 times a minute. Unlike your digestive system the respiratory system is a dead end. If something bad gets into your lungs it's very hard to get it back out. As usual the body has an answer to look very closely at the cells lining the tracker and the bronchi some of them have tiny little hairs on called cilia and in between these cells are other cells called goblet cells that are secreting mucus. This mucus traps dirt dust and bacteria before entered the lungs. The cilia then what this mucus up into the mouth where it can be swallowed to be killed by your stomach acid. There are many things that can go wrong with your lungs such as asthma, pneumonia and diseases associated with smoking such as emphysema and chronic bronchitis. However, if you have a problem a doctor may perform a bronchoscopy. This is when they put a tube with a light and the camera on it into your Airways and look for signs of inflammation or bleeding.

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!

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.
