What type of circulation moves blood from the heart to the lungs and back?

Systemic circulation
Pulmonary circulation
Coronary circulation
Hepatic circulation

The correct answer is: Pulmonary circulation

Pulmonary circulation is responsible for transporting blood from the heart to the lungs and back again. This process begins when deoxygenated blood is pumped from the right ventricle of the heart into the pulmonary arteries, which carry the blood to the lungs. In the lungs, carbon dioxide is exchanged for oxygen through the alveoli, a process essential for gas exchange. Once the blood has been oxygenated, it returns to the heart via the pulmonary veins, entering the left atrium. This circuit is crucial for ensuring that the blood is replenished with oxygen before being distributed throughout the body via systemic circulation. In contrast, systemic circulation refers to the pathway that carries oxygenated blood from the heart to the rest of the body, coronary circulation involves blood supply specifically to the heart muscle itself, and hepatic circulation pertains to the flow of blood between the heart and the liver. Each of these systems serves distinct functions in the body's overall circulatory framework.
