Which circulation moves blood from the heart to the lungs and back?

Explanation:
The circulation that moves blood from the heart to the lungs and back is the pulmonary circuit. The right side of the heart pumps deoxygenated blood to the lungs through the pulmonary arteries. In the lungs, blood picks up oxygen and releases carbon dioxide, then the oxygenated blood returns to the heart, entering the left atrium via the pulmonary veins. This loop is distinct from the systemic circuit, which sends blood to the rest of the body, and from circulations that supply the heart itself or the kidneys.
