Question

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

• A. Only once
• B. Two times
• C. Four times
• D. Several times

Answer 1

The correct option is B

Two times

After entering left atrium of heart, it will be transported to lungs for receiving oxygen. Then it will go into right chamber of heart and will be transported back to liver through aorta and then hepatic artery. Thus, from the above discussion it is clear that red blood cells enter the heart twice in its journey.
