Through which structure does blood flow from the heart to the lungs in the pulmonary circulation?
Left ventricle
Pulmonary artery
Left atrium
Pulmonary veins
The Correct Answer is B
Choice A reason: The left ventricle pumps oxygenated blood into the aorta and then to the rest of the body, not
directly to the lungs.
Choice B reason: The pulmonary artery is the correct answer because it carries deoxygenated blood from the right
ventricle of the heart to the lungs for oxygenation.
Choice C reason: The left atrium receives oxygenated blood from the lungs through the pulmonary veins, so it is not
involved in sending blood to the lungs.
Choice D reason: The pulmonary veins carry oxygenated blood from the lungs to the left atrium, not from the heart
to the lungs.
