What is the normal pH range of blood?

  1. 6.35-6.45

  2. 7.35-7.45

  3. 8.35-10.45

  4. 9.45-10.45

The correct answer is: 7.35-7.45

The normal pH range of blood is 7.35 to 7.45, indicating that the blood is slightly basic. This range is crucial for maintaining proper physiological functions, including enzyme activity, oxygen transport, and acid-base balance. The body uses various mechanisms, such as the respiratory and renal systems, to regulate blood pH within this narrow range. Deviations from this normal range can lead to acidosis (if pH drops below 7.35) or alkalosis (if pH rises above 7.45), both of which can have serious health implications. Thus, the chosen answer accurately reflects the physiological standards for healthy blood pH.
