GENERAL HISTOLOGY

Detailed explanation-1: -Interstitial fluid is a biological fluid present between the cells and tissues, comprising a similar composition to that of the plasma [79]. From: Drug Delivery Devices and Therapeutic Systems, 2021.

Detailed explanation-2: -The interstitial fluid and the blood plasma are the major components of the extracellular fluid. The interstitial fluid is the fluid that fills the spaces between cells. It is composed of water, amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, and cellular products.

Detailed explanation-3: -The interstitial space that lies between blood vessels and cells provides the fluid and structural environment surrounding those cells. Under most conditions in most tissues, fluid from the vascular space continually filters from the microvessels into the interstitial space and is not reabsorbed (1).
