Question

The pH of blood in a healthy human is precisely in the range of \(\underline{\hspace{2cm}}\).

• A. 7.10 – 8.10
• B. 6.95 – 7.05
• C. 7.15 – 7.20
• D. 7.35 – 7.45

Hint:

The pH of blood is tightly regulated in the body. A normal pH range of 7.35 to 7.45 ensures proper cellular function and metabolic processes.

Answer 1

The Correct Option is D

The normal pH of blood in a healthy human body ranges between 7.35 and 7.45, which is slightly basic. The body maintains this pH range through buffering systems, such as the bicarbonate buffer system. Any significant deviation from this range can result in health issues such as acidosis or alkalosis.
Therefore, the correct answer is (D).
