What circulatory system moves blood from the heart to the lungs and back to the heart?

The pulmonary circulation system is responsible for moving blood from the heart to the lungs for oxygenation and then back to the heart to be pumped to the rest of the body. The pulmonary arteries carry deoxygenated blood from the heart to the lungs, where it picks up oxygen, and the pulmonary veins return oxygenated blood back to the heart.
