👉 Fluids in the body, primarily water, serve numerous critical functions and can be broadly categorized into two types: intracellular and extracellular. Intracellular fluids (ICFs) reside within cells and are essential for maintaining cell structure, facilitating biochemical reactions, and regulating cell volume. Extracellular fluids (ECFs), on the other hand, exist outside cells and are divided into interstitial fluid, which surrounds cells, and blood plasma, which fills the spaces between cells and carries nutrients, hormones, and waste products. Together, these fluids maintain homeostasis, support cellular functions, and ensure the body's overall health and proper operation.
