The pH value of human blood is:
- A
7.80
- B
7.35
- C
7.33
- D
6.62
- E
7.05
The pH of human blood is typically maintained between 7.35 and 7.45. This range is slightly basic, as a pH of 7 is considered neutral. The body has several mechanisms to regulate blood pH tightly, including the bicarbonate buffer system. Option B, 7.35, falls within this normal range. Option A, 7.80, is too alkaline for blood, whereas Options C, D, and E (7.33, 6.62, 7.05) are too acidic, indicating varying degrees of acidosis.
This option is incorrect. A pH of 7.80 is slightly too alkaline for blood and falls outside the normal physiological range.
This option is correct. The normal pH range for human blood is approximately 7.35 to 7.45, which is slightly basic.
This option is incorrect. While close, a pH of 7.33 is slightly lower than the typical lower limit of the normal blood pH range.
This option is incorrect. A pH of 6.62 is too acidic for blood and indicates severe acidosis.
This option is incorrect. A pH of 7.05 is below the normal range and suggests acidosis.
