The nurse responds, when the left ventricle contracts, it pushes blood through a valve to the:
Pulmonary artery.
Aorta.
Inferior vena cava.
Pulmonary vein.
The Correct Answer is B
Choice A rationale:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.

The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen.
Choice C rationale:
The inferior vena cava carries deoxygenated blood from the lower half of the body back to the right atrium of the heart, not from the left ventricle.
Choice D rationale:
The pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.
