In what type of circulation does the blood flow between the heart and lungs?

Pulmonary circulation

Explanation:

The pulmonary circulation is the type of circulatory system that involves the flow of deoxygenated blood from the right ventricle of the heart to the pulmonary trunk, which transports the deoxygenated blood through the right and left pulmonary arteries to the capillary beds and arterioles of the lungs. An exchange occurs in the lungs as oxygen is absorbed from the alveoli, while carbon dioxide is released. The oxygenated blood is then returned to the left atrium and ventricle of the heart.
