How the Heart Works
Your heart is a powerful, muscular organ situated barely to the left of your chest. It pumps blood to all elements of the body by a network of blood vessels by repeatedly expanding and contracting. On common, your coronary heart will beat 100,000 occasions and pump about 2,000 gallons of blood every day. The guts is divided right into a proper and left aspect, separated by a septum. Each aspect has an atrium (which receives blood as it enters) and a ventricle (from which blood is pumped out). The center has a total of 4 chambers: right atrium, proper ventricle, left atrium and left ventricle. The suitable facet of the guts collects oxygen-depleted blood and pumps it to the lungs, by way of the pulmonary arteries, in order that the lungs can refresh the blood with a recent provide of oxygen. The left side of the center receives oxygen-rich blood from the lungs, then pumps blood out to the rest of the physique's tissues, through the aorta.
As the guts pumps blood, a series of valves open and close tightly. These valves ensure that blood flows in just one route, stopping backflow. The tricuspid valve is situated between the correct atrium and proper ventricle. The pulmonary valve is between the suitable ventricle and the pulmonary artery. The mitral valve is between the left atrium and left ventricle. The aortic valve is between the left ventricle and the aorta. Each heart valve, apart from the mitral valve, has three flaps (leaflets) that open and shut like gates on a fence. The mitral valve has two valve leaflets. While the guts and lungs are the largest organs of the circulatory system, the blood vessels are the longest. This prolonged community of stretchy tubes circulates blood throughout the body.
