Detailed explanation-1: -Your heart is the primary organ of your circulatory system. It pumps blood throughout your body, controls your heart rate and maintains blood pressure. Your heart is a bit like a house. It has walls, rooms, doors, plumbing and an electrical system.
Detailed explanation-2: -What Are the Parts of the Circulatory System? Two pathways come from the heart: The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.
Detailed explanation-3: -The circulatory system consists of the heart, capillaries, arteries and veins. While arteries carry blood away from the heart, the veins (in most cases) carry blood back to the heart. The capillaries facilitate the exchange of oxygen and nutrients to the cells.
