👉 Fluids, crucial for maintaining bodily functions, are primarily water but also include electrolytes like sodium, potassium, and chloride, as well as smaller amounts of urea, glucose, and other dissolved substances. These fluids are essential for regulating body temperature through sweating and respiration, facilitating nutrient transport and waste removal via blood and lymph circulation, and maintaining the proper functioning of cells and tissues. The balance of these fluids is regulated by the body's homeostatic mechanisms, including the kidneys, which adjust water and electrolyte levels in response to needs. Proper hydration is vital for optimal physiological performance and overall health, ensuring that all bodily systems operate efficiently.
