Although the PH of the Blood is 7

Question

Although the pH of the blood is 7.4, our cells can function well within a pH range of 3.0-11.0.

Accepted Answer

Although some cells in the body can tolerate a slightly broader pH range (such as stomach cells, which can function at a pH of 1.5-3.5), the overall pH range for cellular function is much narrower and closer to the normal blood pH of 7.4.
