👉 The surrounded fluid, also known as the interstitial fluid or extracellular fluid, is a vital component of the human body that fills the spaces between cells and within tissues. It surrounds cells, forming a dynamic network that facilitates the exchange of nutrients, gases, and waste products. This fluid is primarily composed of water, salts, glucose, and various proteins and molecules essential for cellular function. It acts as a medium for biochemical reactions and helps maintain the structural integrity of tissues, ensuring that cells can communicate effectively and perform their physiological roles. Surrounded by a semi-permeable membrane, the fluid can move in and out of cells, playing a crucial role in homeostasis and overall bodily functions.
