What is the pH of human blood?

Last Updated:

What is the pH of human blood? This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. The human body works through coordinated organ systems. Questions may also test blood components, vitamins, glands, sense organs, communicable diseases, and deficiency disorders.

A6.4 to 6.8
B7.0 to 7.2
C7.35 to 7.45
D7.8 to 8.0
Correct Answer: 7.35 to 7.45Your Answer: C

Explanation

The kidneys and lungs work together to regulate blood pH: the lungs control CO₂ levels (respiratory regulation) and kidneys control bicarbonate (metabolic regulation). Blood with this pH would indicate severe acidosis and would be incompatible with life. While blood pH of 7.0-7.2 is above pure acid, it is still below the normal blood pH and would represent dangerous acidosis. 7.8 to 8.0 — This range is more alkaline than normal blood. Normal blood pH is maintained by bicarbonate buffer system (HCO₃⁻/H₂CO₃). The kidneys regulate blood pH by excreting or reabsorbing bicarbonate.
