![]() ![]() There are three arteries of the heart, including pulmonary artery, aorta, and coronary arteries. Arteries are quite tough on the outside but are smooth on the inside. Arteries: These types of blood vessels take oxygen-rich blood from the heart and transport to the capillaries.There are two types of them: arteries and veins. The basic function of these vessels is to take deoxygenated blood from different organs, supply it to the heart, and then take oxygenated blood that comes from the lungs into the heart to the rest of your body.īlood vessels are more like a network that helps circulate blood throughout your body.These vessels connect other organs in your body to your heart. Blood vessels help transport blood to-and-fro from your heart.Aortic valve separates the aorta from the left ventricle and regulate the flow of blood from the ventricle to the rest of your body.It pumps the oxygenated blood into the left ventricle when the left atrium contracts. Similarly, mitral valve has two cusps and is located in a way that it causes a separation between the left ventricle of your heart and the left atrium of your heart.It opens up when the right ventricle contracts and allows the blood to move into the left pulmonary artery. Pulmonary valve is between the left pulmonary artery of your heart and its right ventricle.Tricuspid valve is located between the right ventricle of your heart and the right atrium, and allows the blood to move from the right atrium to the right ventricle.Different valves perform different functions. These valves allow blood flow in one direction only. Every heart diagram labeledwill clearly show these valves. Your heart has four types of valves with primary function of regulating the blood flow through the heart. ![]() Valves to Ensure Unidirectional Blood Flow Your left atrium receives oxygenated blood from the lungs, which is then pumped into the left ventricle from where it moves into the aorta and then to the different parts of your body. Deoxygenated blood enters your heart through the right atria from where the blood moves into the right ventricle first and then to the lungs through the pulmonary artery.The upper chambers of your heart are atria, whereas the lower chambers are ventricles.There are four chambers in your heart that are left atrium, right atrium, left ventricle, and right ventricle. It beats approximately 72 times per minute, and pumps oxygenated blood to different parts of the body. The heart, one of the most significant organs in the human body, is a muscular pump, which pumps blood throughout the body. It is located between the lungs, in the middle of the chest, behind and slightly to the left of the breast bone. The shape of the human heart is like an upside-down pear, weighing between 7-15 ounces, and is little larger than the size of the fist. Four Chambers of the Heart and Blood Circulation ![]() Keep reading to learn more about how your heart works. It provides information about different chambers of the heart and valves that help transfer blood from one part of your heart to another. The function of heart is quite complex, but you can understand things better through the heart diagram labeled below. Heart is a vital organ that you cannot live without. ![]()
