Water moves inside the body by osmosis that carries up or down a concentration gradient, which is dependent on where the water is needed and where there needs to be a reduction if there is an too high of an amount of water.

Sweat cools the body by producing water to lose heat in the body. Water also aids in digestive and excretory functioning. We lose a lot of water through the digestive system because it aids in breaking down the foods we eat and we lose a lot of water through urine and feces.
