The path of blood through the heart begins with the right atrium receiving blood, which has circulated through most of the body. This blood is relatively low in oxygen because most of it has already been delivered to different organs and tissues.
Blood passing through the left side of the heart is kept. separate from blood passing through the right side of the. heart. Thus, the human heart is actually a double pump, right. and left. The right heart receives blood from the systemic. veins and pumps the blood into pulmonary arteries going to. the lungs. The left heart receives blood coming from the. lungs by way of the pulmonary veins and pumps the blood to. the rest of the body. Fig.
