Body water Body water In physiology, body water is the water content of an animal body that is contained in the tissues, the blood, the bones and elsewhere.

Ensuring the right amount of body water is part of fluid balance, an aspect of homeostasis. By weight, the average human adult male is approximately 60% water and the average adult female is approximately 50%. There can be considerable variation
