What is the typical pH level of human blood?

• A. 6.4
• B. 7.0
• C. 7.4
• D. 10.6

Answer: (C)

The typical pH level of human blood is approximately 7.4. This pH range is crucial for maintaining the proper function of various biological processes. Blood that is too acidic (lower pH) or too alkaline (higher pH) can disrupt metabolic activities and affect the overall health of an individual. The body employs various mechanisms, such as respiratory regulation and renal function, to maintain this pH balance within a narrow range, which is vital for enzyme activity, oxygen transport, and overall homeostasis. A pH of 7.4 signifies a slightly basic environment, which is essential for optimal physiological functioning.
