Which blood vessel carries deoxygenated blood from the heart to the lungs?

The blood vessel that carries deoxygenated blood from the heart to the lungs is the pulmonary artery. Here are the steps of how this process works:

1. Deoxygenated blood, or blood low in oxygen and high in carbon dioxide, is collected from the body and returned to the right atrium of the heart through the superior and inferior vena cava.

2. The right atrium contracts and pushes the blood into the right ventricle.

3. The right ventricle then contracts and pushes the blood into the pulmonary artery.

4. The pulmonary artery is unique because it is one of the few arteries in the human body that carries deoxygenated blood. It carries this blood from the heart to the lungs.

5. In the lungs, the blood picks up oxygen and gets rid of carbon dioxide, a waste product of metabolism.

6. The oxygenated blood then travels back to the heart via the pulmonary veins, ready to be pumped out to the rest of the body.
