Human body works in the pH range of:
Options
- A6.8-7.2
- B7.0-7.8
- C6.5-7.5
- D7.5-8.0
Correct answer
B. 7.0-7.8
Step-by-step solution
The human body maintains a tightly regulated pH range to ensure proper physiological function. This range is typically between 7.0 and 7.8 . The optimal pH for most body fluids, particularly blood, is around 7.4 , which is slightly alkaline. Enzyme activity, oxygen transport, and metabolic processes are all dependent on maintaining this pH range. Deviations from this range can lead to serious health issues, as enzymes and other biochemical processes may not function correctly if the pH is too acidic or too alkaline
