WATER AND HUMANS. * The human body is more than 60 percent water. Blood is 92 percent water, the brain and muscles are 75 percent water, and bones are about 22 percent water. * A human can survive for a month or more without eating food, but only a week or so without drinking water.
In medicine, body water is all of the water content of the human body. A significant fraction of the human body is water. Guyton's Textbook of Medical Physiology states that the total amount of water in a man of average weight (70 kilograms) is approximately 40 liters, averaging 57 percent of his total body weight.
