Gas exchange occurs within the alveoli in order that gas is loaded into the blood and carbon dioxide is blank from the blood. Afterward, gas is delivered to the left aspect of the guts via the pulmonary vein, which pumps it into circulation.
Red blood cells carry the gas into the capillaries of the tissues of the body , the gas diffuses into the cells of the tissues, whereas CO2 diffuses out of the cells of the tissues and into the blood.
The factors that influence tissue to gas exchange are almost like the factors of alveolar gas exchange and include partial pressure gradients between the blood and also the tissues, the blood insertion of these tissues, and also the surface areas of these tissues. each of these factors typically increases gas exchange as those factors are enhanced (i.e., a lot of gas diffusion in tissues with additional blood perfusion).
