Question

Within which pH range does our body work?

• A. 4.0 to 4.8
• B. 5.0 to 5.8
• C. 6.0 to 6.8
• D. 7.0 to 7.8

Hint:

The pH of blood and other bodily fluids is tightly regulated to maintain homeostasis, typically between 7.35 and 7.45.

Answer 1

The Correct Option is D

The normal pH range of the human body is slightly alkaline, typically between 7.0 and 7.8. This is the pH range where most biochemical processes occur optimally.
