(A) The blood circulation in humans is a double circulation system. $1$. The blood flows from the hepatic artery to the liver capillaries. $2$. From the liver,the blood enters the hepatic vein,which drains into the inferior vena cava. $3$. The inferior vena cava carries deoxygenated blood to the right atrium of the heart. $4$. From the right atrium,it passes to the right ventricle and then to the lungs via the pulmonary artery for oxygenation. $5$. After oxygenation,the blood returns to the left atrium via the pulmonary veins,enters the left ventricle,and is finally pumped into the aorta. $6$. Thus,in this entire journey,the $RBC$ passes through the heart exactly once to complete the circuit from the systemic venous return to the systemic arterial output.

How many times will a red blood corpuscle $(RBC)$ have to pass through the heart in its journey from the hepatic artery to the aorta?
