Biology - Water

Water

Approximately 70% of the mass of humans is water. The majority of water
comes from drinks but most foods also contain much water. For example 93%
of a watermelon's mass is water.

Water plays many vital roles in plants and animals:

* water is a solvent for many substances in cells

* water is a requirement for many chemical reactions

* wastes [1] are removed from the body in a liquid

* water helps keep the body temperature constant in many animals

* water helps support cells

* our blood transports substances dissolved in water
