Answer 1

pH 7.4 is the optimal pH at which all the enzymes and biochemical reactions would occur in blood and also maintain homeostasis. Probably that's why we have buffering systems which maintains the pH of blood at 7.4 to promote an optimal activity. ... If the pH level is above 7.35 you ll suffer from alkalosis.

Answer 2

hey mate your answer is here

the human body of the ph value is 7.0 to 7.4 if it increase ph value pH is a measure of the acidic or basic (alkaline) nature of a solution (concentration of the hydrogen ion [H+] activity in a solution determines the pH). ... Our blood and other body fluids that surround the cells are slightly alkaline (pH from 7.2 to 7.45).
