I understand that we need for to survive since we break down the nutrients inside for energy, but the use of water confuses me
In: Biology
Virtually all the chemical reactions in our bodies happen “in solution”…the chemicals are dissolved, or at least free floating, in a fluid. For humans (and all other forms of life we know about), that fluid is water.
Water is what lets the molecules that “make us go” move around and interact with each other. Without water we’re a pile of non-reacting chemicals. Try baking a cake without the wet ingredients and you kind of get the idea.
We lose water to our environment constantly, since we’re way wetter than our surroundings and we use some of it to carry waste out of our bodies, so we have to keep replacing it or we shut down and die.
