Question

In which chamber of the human heart the blood is low in Oxygen?

• A. Right atrium
• B. Right ventricle
• C. Left atrium
• D. A and B

Answer 1

The correct option is D A and B

• Humans have a four-chambered heart.
• The two upper chambers are called the atria.
• The lower two chambers are called the ventricles.
• The right atrium receives Oxygen-poor blood from the body and pumps it to the right ventricle.
• The right ventricle pumps the Oxygen-poor blood to the lungs through pulmonary artery for Oxygenation.
• Therefore right atrium and right ventricle are the chambers of the human heart with low Oxygen in the blood.

So, the correct answer is 'Both A and B'.
