Question

pH of human blood is ______.

Options

• 7.8

• 7.35

Answer 1

pH of human blood is 7.35.

Explanation:

Human blood is slightly basic (alkaline), and keeping its pH within this tight range is critical for survival and proper cell function. The body uses chemical buffer systems, along with the lungs and kidneys, to prevent dangerous shifts in blood pH. A drop below 7.35 causes acidosis, while a rise above 7.45 causes alkalosis.
