The hydrogel that surrounds cells in soft tissues. It is a mucopolysaccaride starch gel, and the serum that leaves the blood capillaries flows through this gel, some to return to the exiting venous blood, some to enter the lymph system. There is an old medical axiom: the blood feeds the lymph, and the lymph feeds the cells. Interstitial fluid that flows through the starch colloid is this lymph.
Together with transcellular fluid accounts for 80% of all extracellular fluid in the body consists of body fluids that bathe all body cells.
Fluid located between cells and in some body cavities such as joints, pleura, and the gastrointestinal tract. The fluid provides a medium for passage of nutrients to and from cells.
Part of the extracellular fluid; fluid found between cells of the body that helps to provide a large part of the fluid environment of the body.
The portion of the extracellular fluid that is between the cells and outside the blood and lymphatic vessels.
A clear liquid that bathes all the cells of the body. Interstitial fluid circulates outside the blood and lymphatic vessels; it is filtered from the blood in the capillaries and returns to the bloodstream through the lymphatic system.
The interstitial fluid, often described as the fluid residing between cells within tissues, is commonly referred to as the bodily fluid substance.
