WHAT IS STUCTURE OF HEART
Answers
The heart can be found at the center of the chest, underneath the sternum in a thoracic compartment. It is made up of 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 and receive oxygen-free blood. The valves that separate these chambers are called atrioventricular valves which is 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 all organs of the body, reaching even the smallest cells. Similar to the atria, the ventricular chambers are also separated by valves. Collectively-termed as semilunar valves, these are comprised of the pulmonary and aortic valve.

Humans (Mammals) have a 4-chambered Heart consisting
2 Atria and 2 Ventricles.
- Atria receive blood, while the ventricles pump blood.
- The right atrium receives blood from the superior and inferior vena cavas.
- Blood then moves to the right ventricle where it is pumped to the lungs.
- The lungs re-oxygenate the blood and send it to the left atrium.
- Blood moves from the left atrium to the left ventricle via the bicuspid valve.
- Blood is pumped out of the left ventricle to the aorta, which sends blood to the organs and muscles of the body.
