Flow of blood from the heart to the lungs and back to the heart is called?

• A. Pulmonary circulation
• B. Systemic circulation
• C. Coronary circulation
• D. Renal circulation

Answer: (A)

Pulmonary circulation is the loop that moves blood between the heart and the lungs. It begins when the right ventricle pumps blood into the pulmonary artery toward the lungs. In the lungs, blood releases carbon dioxide and picks up oxygen. The oxygen-rich blood then returns to the heart through the pulmonary veins into the left atrium, completing the circuit. This pathway is distinct from systemic circulation, which sends blood to the rest of the body, and from the heart’s own blood supply (coronary) or kidneys (renal).
