Question: 1 / 400

How does oxygenated blood return to the heart?

Through the inferior vena cava

Through the aorta

Via the pulmonary veins

Oxygenated blood returns to the heart through the pulmonary veins. After oxygenation occurs in the lungs, the blood travels back to the left atrium of the heart via these veins. This is a crucial part of the circulatory system, as it allows the heart to receive oxygen-rich blood and then pump it out to the rest of the body.

The other options primarily involve different aspects of circulation. The inferior vena cava carries deoxygenated blood from the lower body back to the heart, while the aorta is responsible for distributing oxygenated blood from the heart to the entire body. The coronary arteries deliver oxygenated blood specifically to the heart muscle itself, not returning blood to the heart. Understanding the roles of these vessels helps clarify how oxygenated blood is efficiently routed back to the heart for circulation.
