WebAug 10, 2024 · Gas is exchanged in the lungs at the site of the alveoli. The exchange of gases in alveoli is possible because they are surrounded by membranes filled with capillaries. These membranes allow... WebJul 30, 2024 · 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.

WebThe gas used to test the diffusion capacity of the lung is carbon monoxide. Why? Because as you have seen, carbon monoxide is diffusion limited, so any change in membrane characteristics will affect its movement into the bloodstream. So fundamentally, we will have the patient inhale a little carbon monoxide and hold their breath for a few seconds.
