Pulmonary Arteries
The blood vessel that carries deoxygenated (low oxygen) blood away from the heart is called the pulmonary artery. This artery carries blood to the lungs where it picks up oxygen and then travels back to the heart to be pumped out to the cells of the body. The best way to remember this is to remember that pulmonary means lungs and artery means a blood vessel that carries blood away from the heart. Most arteries carry blood that is rich in oxygen. The pulmonary artery is an exception.
