Plants and animals (including people) must drink water to live. It gives a medium for chemical reactions to take place, and is the main part of blood. It keeps the body temperature the same by sweating from the skin. Water helps blood carry nutrients from the stomach to all parts of the body to keep the body alive. Water also helps the blood carry oxygen from the lungs to the body. Saliva helps animals and people digest food. Water helps make urine. Urine helps remove bad chemicals from the body. The human body is 60–70% water.
Water is the main component of drinks like milk, juice, and wine. Each type of drink also has other things that add flavor or nutrients, things like sugar, fruit, and sometimes alcohol. Water that a person can drink is called "potable" (or "drinking") water. The water in oceans is salt water, but lakes and rivers usually have unsalted water. There is only about 3% fresh water on earth, the rest is salt water.
