It carries oxygen and food for cells. It cleans our body and brings the waste in sweat or urine. It also keeps the balance of mineras in our body. Most parts of human body use water to work. We cannot move well if there is not enough water in our body.
Sixty five percent of our body is water. To keep that amount of water in our body we must drink an average of eight to ten glasses of water each day. How much water does a person need everyday.?
