Detailed explanation-1: -(IN-ter-STIH-shul FLOO-id) 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: -Interstitial fluid consists of a water solvent containing sugars, salts, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, white blood cells and cell waste-products.
Detailed explanation-3: -Extracellular fluid (ECF) surrounds all cells in the body. Extracellular fluid has two primary constituents: the fluid component of the blood (called plasma) and the interstitial fluid (IF) that surrounds all cells not in the blood (Figure 2).
Detailed explanation-4: -Interstitial fluid is a biological fluid present between the cells and tissues, comprising a similar composition to that of the plasma [79].
Detailed explanation-5: -Sugars, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, minerals such as sodium, chloride, calcium, magnesium, and potassium, and metabolic waste products are all found in interstitial fluid. Intercellular exchange and blood in the particular tissue determine the composition of interstitial fluid.
