Structure of the heart:
The heart can be found at the chest's center, underneath the sternum in a thoracic compartment. It comprises four chambers and several valves that regulate the normal flow of blood within the body.
Two chambers called atria are located in the upper portion of the heart with the left atrium receiving oxygen-rich blood and the right receiving oxygen-free blood. The valves that separate these chambers are called atrioventricular valves, composed of the tricuspid valve on the left and the mitral valve on the right.
On the other hand, ventricles are chambers found on the lower portion of the heart; they pump oxygen-enriched blood into the body's organs, reaching even the smallest cells. Similar to the atria, valves also separate the ventricular chambers. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valves.
