Why do we need water to stay alive?



  1. 0 Votes

    Our bodies are about 70% water.  Without it our cells would dry up and the stuff inside them, like DNA, RNA and proteins would not be able to move or carry out their functions.  We need water to keep our bodies, from our eyeballs to our toes hydrated and allow our cells to function properly.

    Water plays an important role in all of the body’s functions.  The brain is made of mostly water, and it sends electrical signals which are conducted by water to the muscles and organs of the body.  Blood is made of mostly water, and wouldn’t be able to flow through arteries, veins, and capillaries to give oxygen to the body if it dried up.  When you eat food, a large amount of water is required to take nutrients from the food to power your body, and also to push the food along your digestive tract. 

    Water is like the body’s engine oil: it lubricates, cools, and keeps things moving.  If we don’t drink enough water, our bodies will not be able to function, and we will die.
