What is the normal pH range for healthy human blood?

• A. 7.25 - 7.35
• B. 7.35 - 7.45
• C. 7.45 - 7.55
• D. 7.55 - 7.65

Answer: (B)

The normal pH range for healthy human blood is generally accepted to be between 7.35 and 7.45. This range is crucial for maintaining various physiological processes, as even slight deviations can lead to significant health issues. Blood pH affects oxygen transport, enzyme activity, and overall metabolic functions. When blood pH drops below 7.35, it may indicate acidosis, which can occur due to conditions such as respiratory failure or metabolic disorders. Conversely, a pH above 7.45 can indicate alkalosis, which may arise from respiratory issues or excessive base accumulation. Maintaining blood pH within this narrow range is vital for homeostasis, underscoring the importance of the correct answer in understanding the body's biochemical balance.
