WebThe alveoli have a lining of thin and squamous epithelium, that allows for gas exchange. The squamous epithelium forms the structure of the alveolar wall and so is very thin and permeable for the easy diffusion of gases. Smooth muscle can be found throughout the walls of the bronchi and bronchioles. It helps to regulate the flow of air into the ... WebGas Exchange explains how four processes—delivery of oxygen, excretion of carbon dioxide, matching of ventilation and perfusion, and diffusion—allow the respiratory system to maintain normal partial pressures of oxygen (PaO 2) and carbon dioxide (PaCO 2) in the arterial blood.
