Why is water important to the body homeostasis?
Water accounts for 2/3 of body weight and it is the most abundant of inorganic compound in the body
Water has a high heat capacity; it can absorb and release large amounts of heat before its temperature changes. It prevents sudden changes in body temperature from occurring.
Because of its polarity, water is an excellent solvent; sometimes called the universal solvent. Because nutrients, respiratory gases (oxygen and carbon dioxide), and wastes can dissolve in water, water can act as a transport and exchange medium in the body.
Water is an important reactant in some types of chemical reactions such as digesting food, or the breaking down of biological molecules.
Water also serves as a protective function such as the cerebrospinal fluid. Water forms a cushion around the brain.
