WebApr 1, 2024 · Epithelial cells have many roles in an organism, such as playing a part in secretion, absorption, sensation, protection and transport. For example, they offer protection for the skin and stop pathogens from entering. Epithelial cells form a barrier that keeps you safe. They act like gatekeepers. WebBasic Principles of Gas Exchange. Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide ...
