WebGas 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 … WebThere are three main gases in air that are taken in and removed from the body. These are oxygen, nitrogen and carbon dioxide. Gas exchange is the ‘swapping’ of gasses - …

As described in oxygen pulmonary gas exchange, diffusion of oxygen from the alveolar space to the pulmonary capillaries in a healthy lung is normally perfusion-limited.
