Q:

What is the function of tissue fluid?

A:

Quick Answer

Tissue fluid acts as a fuelling station in terms of cell nutrients, and it is the main component of the extracellular fluid, which also includes transcellular fluid and plasma. Tissue fluid contains glucose, fatty acids, salt and minerals such as calcium, potassium and magnesium. The nutrients of the tissue fluid come from blood capillaries. Tissue fluid can also hold waste products resulting from metabolic processes.

Full Answer

Tissue fluid, also known as interstitial fluid, is a thin layer of fluid that surrounds the body’s cells. This fluid is used to monitor glucose levels. Cells that are suspended in tissue fluid are protected from damage that can be caused by the vibrations of an animal’s movement. Tissue fluid also acts as a medium for sending chemical messages across cells. Tissue fluid makes up about 40 percent of the water in the human body, which accounts for almost one-sixth of human body weight. This fluid is found in the interstitial, or tissue, spaces. Exchange of tissue fluid, gases, nutrients and wastes between the blood and body tissues takes place in the capillaries. The small pores within capillaries allow for a selective passage of substances in and out of the capillaries through diffusion. Blood pressure, or hydrostatic pressure, and the blood within the vessel control the process of fluid exchange.
