WebMay 12, 2024 · Internal respiration is gas exchange that occurs at the level of body tissues (Figure 22.4. 3 ). Similar to external respiration, internal respiration also occurs as simple diffusion due to a partial pressure gradient. However, the partial pressure gradients are opposite of those present at the respiratory membrane. WebDiffusion is the main mechanism of gaseous exchange, which involves movement of a substance from high- to low-concentrated areas. The basic 3 components of external respiration are surface area of alveolar membrane, partial pressure gradient of gases, and ventilation and perfusion matching. mittleman brothers aimiaWebGas 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.

WebFeb 24, 2024 · Partial pressure ( Px) is the pressure of a single type of gas in a mixture of gases. For example, in the atmosphere, oxygen exerts a partial pressure, and nitrogen exerts another partial pressure, independent of the partial pressure of oxygen (Figure 22.5. 1 ). Total pressure is the sum of all the partial pressures of a gaseous mixture.
