Why almost 75% of brain is water?
Possible reasons:
1. Brain works continuously and hence needs more energy and also electrolytes for producing electric impulses. Fluid (blood/water) is the only medium to transport energy, electrolytes in our body.
2. During the function, brain produces approximately 20 watts of energy everyday. There should be some way of removing that heat. Also brain has so many grooves, patterns on it making the surface area of brain bigger. In addition to this, fluid supports in removing the heat.
