Interstitial Fluid

Interstitial fluid, a crucial component of the body's internal environment, plays a pivotal role in maintaining cellular function and homeostasis. Situated between cells and capillaries, this fluid serves as a medium for transporting nutrients, hormones, and waste products throughout tissues. Composed primarily of water and electrolytes, interstitial fluid facilitates the exchange of substances between blood vessels and cells, ensuring proper cellular nourishment and waste removal. Its composition and volume are tightly regulated to support cellular activities and physiological processes. Understanding the dynamics of interstitial fluid is fundamental to comprehending various aspects of human physiology and pathology.
