Answer
Inferior vena cava
Explanation
## Step 1: This question is about the circulatory system and requires understanding of the roles of different blood vessels. The structure that carries blood back to the heart from the lower part of the body is a vein, as veins carry blood towards the heart.## Step 2: Among the options, the pulmonary vein, aorta, and pulmonary artery are not correct. The pulmonary vein carries oxygenated blood from the lungs to the heart, the aorta carries oxygenated blood from the heart to the rest of the body, and the pulmonary artery carries deoxygenated blood from the heart to the lungs.## Step 3: The superior vena cava and inferior vena cava are the two large veins that carry deoxygenated blood from the body back to the heart. The superior vena cava carries blood from the upper part of the body, while the inferior vena cava carries blood from the lower part of the body.
