Question

multiple choice question
the pulmonary trunk is attached to which heart chamber?

left atrium
right ventricle
right atrium
left ventricle

Explanation:

To determine the heart chamber attached to the pulmonary trunk, we recall the heart's anatomy: the right ventricle pumps deoxygenated blood into the pulmonary trunk, which then carries it to the lungs for oxygenation. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the left ventricle pumps oxygenated blood to the body. So the pulmonary trunk is attached to the right ventricle.

Answer:

B. Right ventricle
