The influence of venous admixture on alveolar dead space

Gas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. 2009-06-01 These capillaries and the walls of alveoli share a very thin membrane that allows oxygen from inhaled air to pass through the walls of alveoli and enter the bloodstream via the capillaries. At the same time, carbon dioxide is pushed out in the same way when the air is exhaled.

2017-08-22 Good blood supply and proper ventilation ensure that steep carbon dioxide and oxygen concentration gradients are maintained. During gas exchange, oxygen diffuses from the alveoli, across the alveolar membrane and capillary wall, into the bloodstream, to be picked up by the RBCs. Carbon dioxide diffuses from the blood into the alveoli.

Oxygen is passed from the alveoli into the bloodstream, which then distributes it to cells where it is used to unlock energy from food. 6.4.3 Describe the features of alveoli that adapt them to gas exchange.

They have very steep concentration gradients maintained by the movement of blood and the inspiration and expiration of air. During gas exchange, oxygen diffuses from the alveoli, across the alveolar membrane and capillary wall, into the bloodstream, to be picked up by the RBCs. Carbon dioxide diffuses from the blood into the alveoli. About this Quiz. This is an online quiz called Alveoli and pulmonary capillaries : gas exchange.
