👉 Peripheral fluid, also known as interstitial fluid, is the fluid that fills the spaces between cells in the body's tissues, forming a crucial part of the circulatory system. It acts as a medium for the exchange of nutrients, gases, and waste products between blood vessels and cells. This fluid is derived from plasma that leaks out of capillaries and from the breakdown of red blood cells. Peripheral fluid plays a vital role in maintaining tissue homeostasis, supporting cell function, and facilitating the transport of substances necessary for cellular metabolism and repair. It also helps in the removal of metabolic waste products from cells, ensuring overall tissue health and function.
