Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Blood from the hepatic artery enters the systemic capillaries, returns to the right atrium, passes to the right ventricle, goes to the lungs, returns to the left atrium, and then to the left ventricle. In a complete circulatory circuit, blood passes through the heart twice (once through the right side, once through the left side).
