The human gas exchange system - Structure and alveoli

WebAt the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body. Gas Exchange WebContinuous blood flow in the capillaries and constant breathing maintain this gradient. Each time you inhale, there is a greater concentration of oxygen in the air in the alveoli than … WebAlveolar Pool is higher than atmospheric PCO 2 because carbon dioxide enters alveoli from pulmonary capillaries. P02 is positively correlated with: (1) PO 2, of atmospheric air, (2) rate of alveolar ventilation and inversely correlated with, and (3) rate of oxygen consumption. thoth json
