Document Summary

Delivers nutrients and removes waste from cells. Makes up about 60% of your body weight. Found throughout your body, males have a larger percentage of water throughout their body (less fat, more muscle, need more fluid). Muscle is 75% water, fat is 20% water. Body needs more water per day than any other nutrient, one can survive a deficiency of any other nutrient sometimes for months or years but not water. Cells cannot directly regulate the passage of water across their membranes. Water content of cells is regulated by major minerals that form salts which are dissolved in body fluids. You need about 10. 25 cups a day of water so that input can match output (i. e. urine and sweat). Blood routed through capillaries in the skin gets rid of excess heat. Water intoxication - drink too much water and die.
