Pulmonary Artery

We just learned about the right ventricle pumps deoxygenated blood out of the heart to get filled up with oxygen at the lungs.

The deoxygenated blood leaves the heart through the pulmonary artery and goes to the lungs in capillaries.

It might seem strange that even though it is carrying deoxygenated blood it is called an artery instead of a vein.

The reason it is called an artery is because it is bringing blood away from the heart, and veins all pump toward the heart. So after the blood gets filled with oxygen, it brings oxygenated blood back to the heart in the pulmonary vein
