Water is the basis of life. Without it, life is not possible. Here are important notes regarding to water as the basis of life:

  • Water accounts for up to 75 percent of the weight of the human body.
  • Water provides a relatively stable medium in which chemical reactions can take place.
  • Water’s unique chemical properties (as a solvent with a high boiling point and high heat capacity) make it essential for homeostasis.
  • The body’s thermoregulation relies on water’s high heat capacity to buffer it against swings in external temperature.
  • Cooling of the body is carried out by evaporative water loss—perspiration.
  • Water is also vital as a transport medium.
  • Oxygen is carried by red blood cells suspended in serum, which is mostly water.
  • Nutritional substances are dissolved in water and transported to cells.
  • Water is used to dissolve and dilute waste molecules.
  • If the body is deprived of water for very long, death will result.
