The main function of the heart is to supply oxygen and nutrient-rich blood to all the body. Heart performs this task 3 to 5 times a minute and 5 million 2 million times a year through expansion and contraction. Blood less oxygen-rich blood enters the right atrium and more oxygen-rich blood from the lungs enters the left atrium at the same time.The contraction of the atrium is then transmitted to the right or left ventricle at the same time, with the tricuspid valve in the right atrium and the blood atrium in the left atrium at the same time. Having these valves, one cell is different from the other.When two of these cells are filled with blood and reach a certain level of blood pressure, the cells are compressed. This contraction causes the blood of the right ventricle to reach the lungs through the pulmonary artery on the path of the pulmonary artery, and blood in the left ventricle is transmitted through all the organs of the body through the aorta through the aortic vessel.When the blood in one cell enters the other room, the leaf cells are open and the other valves are closed. That is, the aortic and pulmonary arteries are closed when the mitral and ectopid valves are good. Again, when the pulmonary and aortic valves are open, the tricuspid and mitral valves are closed. This allows the heart’s blood to enter the front room only, and the blood closes as the valves are closed The beads cannot flow into the back room during compression.This is the characteristic of the valves, that is, its doors open in the normal direction on the same side and only blood can flow in the same direction. The doors of the valves remain but until the blood in the front room is being transported to another room by contraction. When this process is finished, the front valve is closed and the preferred valve is opened. The two valves in the same direction are opened simultaneously.
There is a wall between the right and left atrium, called the inter atrial septum, and the wall between the right and left ventricles is called the inter ventricular septum. The outer muscle of the heart is covered by two thin layers,There is what is called pericardium.The two layers of pericardium contain a small amount of water. The function of this water is to separate the two layers from one to the other. The coronary artery (blood vessel) is attached to the outside of the heart wall by its branches as a root. The function of these arteries is to provide blood to the heart muscle and other parts of the heart. It is through this blood that the heart gets its oxygen and nutrients.The right side of the heart is more active while in the womb, and blood from the right atrium goes to the left atrium with the oval of the forum. We also see that blood enters the aorta through the ductus arteriosus from the pulmonary artery. When the infant starts breathing after landing, these paths are closed. But when both of these pathways cannot be closed, atrial septal defect and patent ductus arteriosus (PDA) cause congenital heart disease.
