What is the normal pH level of blood?

• A. 6.8-7.2
• B. 7.0-7.4
• C. 7.35-7.45
• D. 7.5-7.7

Answer: (C)

The normal pH level of blood typically ranges from 7.35 to 7.45, which is crucial for maintaining homeostasis in the body. This range ensures optimal conditions for enzymatic functions and metabolic processes. A pH below 7.35 indicates acidosis, while a pH above 7.45 indicates alkalosis, both of which can cause serious health complications. The precise control of blood pH is vital for various physiological functions, including oxygen transport, carbon dioxide regulation, and overall cellular activities. This is why the choice indicating a pH level of 7.35 to 7.45 is the correct answer.
