Pulmonary Vein

We've learned that our blood gets filled up with good oxygen in the capillaries down by the lungs.

After the tiny capillaries are filled up with good oxygen, they connect to larger tubes called veins, and the blood flows toward the heart.

The veins that connect the capillaries to the heart are called the pulmonary veins.
