Question

Quizplus · Accepted Answer

The pulmonary circulation connects the heart and lungs, carrying deoxygenated blood from the heart to the lungs to be oxygenated and then returning oxygenated blood to the heart. The systemic circulation connects the heart to the rest of the body, delivering oxygenated blood and nutrients to the tissues and organs and carrying away waste products. The aortic and cardiac circulations are not separate circuits, but rather parts of the systemic circulation, with the aorta being the largest artery in the body and the cardiac circulation referring to the blood flow within the heart itself.
