Question

How many times a red blood corpuscle will have to pass through the heart in its journey from hepatic artery?

• A. Once
• B. Two times
• C. Four times
• D. Several times.

Answer 1

The correct option is B Two times

B. Two times

Reason: Double circulation occurs in human heart. So the blood present in hepatic artery get spread throughout the body and become deoxygenated. Then it will come to right atrium of the heart and sent towards lungs. After becoming oxygenated, it will come to to left atrium of the heart and reach to hepatic artery again. Red blood cells are present in blood. So, option B is correct.
