Which of the following is NOT a function of water in the body?

Water plays several essential roles in the body, and understanding its functions helps clarify why certain options are included in the list while others are not.

Regulating body temperature is primarily achieved through the process of sweating and evaporation. When the body heats up, sweat is produced and, upon evaporating from the skin surface, it cools the body down.

Water also serves as a lubricant in joints, which is necessary for smooth movement and reducing friction between joint surfaces during activity.

Furthermore, water acts as a solvent for many nutrients. It helps dissolve vitamins, minerals, and other substances, making it easier for the body to absorb and utilize these essential nutrients.

While water does play a crucial role in overall bodily functions, it does not transport oxygen to cells directly. Oxygen is transported primarily by hemoglobin in red blood cells, not by water itself. Therefore, the statement that water is responsible for transporting oxygen to cells is not accurate.
