Water is the elixir of life. By far the largest percentage of the animal body, all living organisms and goring plants consist of moisture. Even their shape or form is attributed to their moisture content. Water is of such importance to the animal that it will succumb sooner from a lack of water or thirst than from hunger. All body cells and interstitial spaces contain moisture acting as a vehicle for nutrients in the body. In the same way, water or moisture in the roots of plants is the vehicle for the absorption of minerals from the soil.
The complicated biochemical reactions of bodily functions, digestion and absorption, depend upon the moisture content of plants and animals. From 75 – 85% of an animal’s mass may be attributed to water, while green plants contain 70 – 90% moisture.
