The heart, as it is known, is located in the right part of the chest. It is a musculature that is used to pump blood to the lungs and to the rest of the body through a large artery called the aorta or aorta. If we follow the blood circulation and the work of the heart, we find that the first stages of this interrelated process begins with the arrival of oxygen-free blood from various parts of the body through the veins to the right side of the heart where the blood first in the upper chamber of the upper chambers of the heart and Which is called the right atrium (due to its relative proximity to the ears compared to the lower chambers called the ventricle due to its relative proximity to the abdomen). After the blood reaches the right atrium, it descends into the lower right ventricle (right ventricle) through a valve (controlling blood entry down and preventing its return to the top) called triglyceride. The right ventricle then pumps blood to the lungs through a large artery called the pulmonary artery through the pulmonary valve, which allows the blood to exit but at the same time prevents it from returning to the right ventricle. When the blood reaches the lungs, the lungs add oxygen (blood oxidation) to the blood. Afterward, the oxidized blood returns to the left upper chamber of the heart (the left atrium) through four veins called pulmonary veins. The left ventricle, the strongest ventricle, pumps blood to all organs of the body through the aorta through the aortic valve.
