WebJan 23, 2024 · Gas exchange occurs in the lungs between alveolar air and the blood of the pulmonary capillaries. For effective gas exchange to occur, alveoli must be ventilated and perfused. Ventilation (V) refers to the flow of air into and out of the alveoli, while perfusion (Q) refers to the flow of blood to alveolar capillaries. WebGas Exchange explains how four processes—delivery of oxygen, excretion of carbon …

WebSep 26, 2024 · Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries. Both are important in gas exchange, as ventilation must be sufficient to create a high partial pressure of oxygen in the alveoli. WebThe purpose of the respiratory system is to perform gas exchange. Pulmonary ventilation …
