1. Either of two spongy organs in the chest of air-breathing vertebrate animals that serve as the organs of gas exchange. Blood flowing through the lungs picks up oxygen from inhaled air and releases carbon dioxide, which is exhaled. Air enters and leaves the lungs through the bronchial tubes...
Before reaching the gas exchange regions of the lungs, air flows through the conducting airways, which are the anatomic structures from the nares to the bronchioles. Because gas exchange does not occur in these locations, they are termed anatomic dead space (Fig. 45.5). Dead space, which r...
A Lung Flow Volume Curve is a graph that shows the relationship between the flow of air in and out of the lungs and the volume of air inhaled or exhaled over time, indicating acceptable lung function. AI generated definition based on: Nursing Clinics of North America, 2003 ...
Apparatus for testing the volume of air from the lungsMichael Benedict
This has to do with the inhaling and exhaling of air into and out of the lungs. On average, a human being can retain 6.3 quarts (6 liters) of air in his lungs at any one time. The capacity of the lungs that is needed for regular breathing uses a very small proportion of this,...
The meaning of EXPIRATORY RESERVE VOLUME is the additional amount of air that can be expired from the lungs by determined effort after normal expiration.
Total lung capacity is the maximal amount of air the lungs and respiratory passages can hold after a forced inspiration. Forced vital capacity is vital capacity performed with a maximally forced expiration. Residual volume is the maximal amount of air left in the lung after a maximal expiration....
Breathing in and out changes the volume of air in the lungs. The four pulmonary volumes can be measured to use as guidelines inhealth assessments. Thetidal volumeis the amount of air taken in or inhaled in a single breath during normal breathing, usually while the person is resting. ...
