Gas exchange in lungs physiology
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.

WebThe movement of fresh air into the lung (inspired) or out of the lung (exhaled) is called ventilation. Both the rate and size of the breath (tidal volume) can change in response to needs of the body. Anatomy The respiratory system consists of structures involved in moving air into and out of the lungs (bulk flow) and in gas exchange (diffusion). WebThe major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.
