Aorta

Pulmonary artery

Pulmonary vein

Superior vena cava

Verified step by step guidance

Understand the function of each vessel listed in the options. The aorta carries oxygen-rich blood from the heart to the rest of the body, so it is not responsible for delivering oxygen-poor blood to the lungs.

Recognize that the pulmonary vein carries oxygen-rich blood from the lungs back to the heart, which means it does not deliver oxygen-poor blood to the lungs.

Identify that the superior vena cava is responsible for bringing oxygen-poor blood from the upper part of the body to the heart, not directly to the lungs.

Focus on the pulmonary artery, which is unique because it carries oxygen-poor blood from the right ventricle of the heart to the lungs for oxygenation.

Conclude that the pulmonary artery is the vessel that delivers oxygen-poor blood to the lungs, as it is the only artery that carries deoxygenated blood in the circulatory system.
