What is the name of the vein that carries oxygenated blood to the heart from the lungs?

The vein that carries oxygenated blood to the heart from the lungs is called the pulmonary vein. This vessel plays a crucial role in the circulatory system as it transports oxygen-rich blood that has been freshly oxygenated in the lungs back to the left atrium of the heart. This process is vital for maintaining the body’s oxygen supply.

Blood from the lungs is oxygenated through gas exchange—carbon dioxide is expelled and oxygen is absorbed. Once this oxygenated blood enters the left atrium via the pulmonary vein, it can then be pumped into the left ventricle and distributed to the rest of the body through the aorta.

Other veins mentioned, such as the jugular vein, inferior vena cava, and superior vena cava, serve different functions. The jugular vein carries deoxygenated blood from the head to the heart but is not involved in transporting blood from the lungs. The inferior and superior vena cavae also transport deoxygenated blood—specifically, from the lower and upper parts of the body, respectively—to the right atrium of the heart, where it then goes to the lungs for oxygenation.
