Question: 1 / 400

What is the term for the fluid found between cells in tissues?

Plasma

Interstitial fluid

The term for the fluid found between cells in tissues is interstitial fluid. This fluid plays a crucial role in the body by facilitating the exchange of nutrients, waste products, and other substances between blood and cells. It serves as a medium where metabolic waste can be transported away from cells, and nutrients can be delivered to them, thus maintaining homeostasis.

Interstitial fluid makes up a significant component of the extracellular fluid environment, which includes all body fluids outside of cells. In contrast, plasma refers specifically to the liquid component of blood, while intracellular fluid is the fluid contained within cells. The extracellular matrix is a network that provides structural and biochemical support to surrounding cells, but it is not a fluid per se. Interstitial fluid directly impacts cellular function and overall tissue health, emphasizing its importance in physiological processes.
