Water is of major importance to all living things; in some organisms, up to 90 percent of their body weight comes from water. Up to 60 percent of the human body is water, the brain is composed of 70 percent water, and the lungs are nearly 90 percent water. About 83 percent of our blood is water, which helps digest our food, transport waste, and control body temperature.
Due to their low body fat and bone mass, infants are about 73% water. The body water content of men is about 60%, but since women have relatively more body fat and less skeletal muscle than men, theirs is about 50%. Total body water is a function of age, body mass, and body fat. Due to their low body fat and bone mass, infants are about 73% water. The body water content of men is about 60%, but since women have relatively more body fat and less skeletal muscle than men, theirs is about 50%. Body water declines throughout life, ultimately comprising about 45% of total body mass in old age.
