Question

What structure of the heart receives oxygen-poor blood from the body, then pumps the blood into the right ventricle?

Answer 1

right atrium

One path of blood in the heart is through the right atrium and right ventricle. The right atrium receives oxygen-poor blood from the body. It pumps the blood into the right ventricle. Then the right ventricle pumps the blood out of the heart to the lungs. This path through the heart is part of the pulmonary circulation.
