Document Summary
Involved in chemical reactions such as hydrolysis and condensation. Blood is made up of about 90% water. Muscle is about 75% water (bone is 25%) Water balance: our water intake is typically the same as our water loss which is why we need to constantly replenish liquid. This claim has become somewhat of an accepted wisdom and is very easy to remember. Bottom line: there is no scientific evidence to support the 8x8 rule. Water intake varies by individual and you should let thirst guide your intake. Baroreceptors sense decrease in bv (sense pressure changes by responding to change in the tension of the arterial wall) stimulates thirst centre and stimulates adh to keep fluid from leaving the kidney tubules. Changes in body water amount and distribution can be life threatening. Infants and athletes can be at higher risk for dehydration.
