Interstitial Fluid

Interstitial fluid (also known as tissue fluid) is a fluid located in spaces between cells in the body, within a tissue or organ. It plays an important role in the regulation of the body’s internal environment, providing nutrients and carrying away waste products. It is also involved in the functioning of organs such as the heart, kidney, brain, and lungs. Interstitial fluid is essential to the body’s homeostasis, the balance of physical conditions, and it helps to ensure the proper functioning of organs and cells. It is also a major component in the lymphatic system which plays a role in the body’s immune response and helps filter out foreign substances. Interstitial fluid is therefore vital to the normal functioning of the body and its continued health.
