Interstitial fluid bulk flow

WebBulk Flow. The mass movement of fluids into and out of capillary beds requires a transport mechanism far more efficient than mere diffusion. This movement, often referred to as bulk flow, ... This opposing hydrostatic pressure is called the interstitial fluid hydrostatic pressure (IFHP). WebDiffusion of a gas occurs when there is a net movement of molecules from an area in which that particular gas exerts a high partial pressure to an area in which it exerts a lower partial pressure. Movement of a gas by diffusion is therefore different from the movement of gases through the conducting airways, which occurs by “bulk flow” (mass movement or …

WebThe circulatory system is the primary method used to transport nutrients and gases through the body. Simple diffusion allows some water, nutrient, waste, and gas exchange in animals that are only a few cell layers thick; however, bulk flow is the only method by which the entire body of larger, more complex organisms is accessed.
