Which vessels carry oxygenated blood from the lungs to the heart?

The vessels that carry oxygenated blood from the lungs to the heart are the pulmonary veins. After the process of gas exchange occurs in the lungs, oxygen-rich blood is collected by the pulmonary veins and transported directly to the left atrium of the heart. This is a crucial aspect of the circulatory system, as it allows the heart to pump oxygenated blood throughout the body.

In terms of the other choices, the superior vena cava and inferior vena cava carry deoxygenated blood from the body back to the heart, specifically to the right atrium. The pulmonary arteries, on the other hand, carry deoxygenated blood from the heart to the lungs for oxygenation. Thus, the pulmonary veins play the significant role of returning oxygenated blood, making them the correct answer in this context.
