Interstitial fluid Notes:

The interstitial fluid and the plasma make up about 97% of the extra cellular fluid, and a small percentage of this is lymph. Interstitial fluid is fluid that surrounds cells, providing them with nutrients and removing their waste products. Eleven liters of the ECF is interstitial fluid and the remaining three liters is plasma. Plasma and interstitial fluid are very similar because water, ions, and small solutes are continuously exchanged between them across the walls of capillaries, through pores and capillary clefts. Interstitial fluid consists of a water solvent containing sugars, salts, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, white blood cells and cell waste-products. This solution accounts for 26% of the water in the human body.
