Question

Pulmonary veins:

O transport blood rich in carbon dioxide to the lungs.
O transport oxygenated blood to the lungs.
O return blood to the right atrium of the heart.
O transport oxygenated blood to the heart.
O split off the pulmonary trunk.

Answer 1

Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

Step-by-step explanation:

The pulmonary veins play a crucial role in the pulmonary circulation of the blood. Different from most veins, the pulmonary veins are the only veins in the body that carry oxygenated blood. Specifically, they transport oxygen-rich blood from the lungs back to the left atrium of the heart. This is a vital part of the cardiac cycle, as it ensures that oxygenated blood can then be pumped throughout the body via the systemic circulatory system. The right answer to the student's question is that pulmonary veins transport oxygenated blood to the heart.
