If you mean "How much percentage of water does a human brain have?", the answer is about 77-78%.
Yes water can make your brain cells grow, but too much water will make your brain cells burst.
your brain is 85% water but the amount in milimeteres or litres depends on the person
a little bit less than 30% of the brain is water <3 hope this helps you if u are into meds like me
it is 80% not 90%
Human brains are75% water
so that it can function properly. your brain is 85% water and if you dont drink lots of water then you will not think straight and you wont function properly
Osmosis is the movement of water from a High Water (Dilute Solution) to a Low Water (Strong Solution). If blood plasma becomes very dilute with water, when it travels to the brain the brain cells will swell because the are taking on too much water. This happens because the high concentration of water (in the blood) is moving to the lower concentration of water (brain cells) making the cells swell as they are taking on too much water.
The brain is 80% water
60 % of the human dody is water; the brain is 70%, the lungs are 90%, and blood is 75% water
water does effect your brain
Well it is just like any part of our body.
