Question
Why is water an essential nutrient?
Advertisements
Solution
- Our body consists of about 65-70% water. Cells and blood plasma contain 70% and 90% water respectively.
- Water acts as a universal solvent as it provides a medium for many metabolic reactions.
- It also helps in the transportation of dissolved nutrients to various parts of the body.
- When there is a little loss of water from the body, the functioning of the cell and thereby the whole body gets disturbed.
Hence, water is an essential nutrient.
