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. WebJan 28, 2024 · The process of pulmonary diffusion is a vital part of respiration and refers to the movement of gases between the alveoli and blood. This exchange is necessary in order to ensure that oxygenated …
WebVentilation is the movement of air into and out of the lungs, and perfusion is the flow of blood in the pulmonary capillaries. For gas exchange to be efficient, the volumes … 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
