Detailed explanation-1: -Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
Detailed explanation-2: -Alternate Synonyms for “interstitial fluid": extracellular fluid; ECF.
Detailed explanation-3: -It is derived from blood plasma as fluids pass through capillary walls at the arterial end. As the interstitial fluid begins to accumulate, it is picked up and removed by tiny lymphatic vessels and returned to the blood. As soon as the interstitial fluid enters the lymph capillaries, it is called lymph.
Detailed explanation-4: -Edema occurs when an excessive volume of fluid accumulates in the tissues, either within cells (cellular edema) or within the collagen-mucopolysaccharide matrix distributed in the interstitial spaces (interstitial edema) [14, 42, 62, 64, 87, 88, 141, 215, 247, 279].
