What is "pulmonary vein"?

The pulmonary veins are a set of four blood vessels that transport oxygenated blood from the lungs to the heart. Two pulmonary veins arise from the left lung and two from the right lung. They are responsible for delivering oxygen-rich blood back to the heart, where it is then pumped to the rest of the body to nourish tissues and organs. The pulmonary veins play a vital role in systemic circulation and are essential for maintaining a healthy oxygen supply throughout the body.

Examples

1. And going back to the heart are the pulmonary veins.

2. So we're talking about pulmonary veins.

3. Pulmonary vein comes from the lungs to the heart with oxygen, but the rest of the veins go to the heart without oxygen because they want to go into that loop on the pulmonary loop right there.

4. And in the left atrium, the blood is entering-- and remember, the left atrium is on the right-hand side from our point of view-- on the left atrium, the blood is entering from above from the lungs, from the pulmonary veins.
