WebDec 31, 2024 · While individual structures may vary depending on a person's individual anatomy, the typical alveoli are roughly 200 micrometers in diameter. ... Gas exchange occurs across this membrane and is ... WebVentilation and Perfusion. Two important aspects of gas exchange in the lung are ventilation and perfusion. Ventilation is the movement of air into and out of the lungs, and perfusion is the flow of blood in the pulmonary capillaries. For gas exchange to be efficient, the volumes involved in ventilation and perfusion should be compatible.

WebGas exchange is a process that involves the swapping of gases that occurs at exchange surfaces such as the alveoli found within your lungs. WebFrom OpenStax Anatomy and Physiology. Internal Respiration. Internal respiration is gas exchange that occurs at the level of body tissues (Figure 2). Similar to external respiration, internal respiration also occurs as simple diffusion due to a concentration gradient.
