He¥ mate here is ur answer✌
➡Function of heart :-
As a central part of the circulatory system, the heart is primarily responsible for pumping blood and distributing oxygen and nutrients throughout the body. Because of this task, the heart may be considered one of the most important organs of the body, such that even small dysfunctions or abnormalities may cause drastic changes or effects in the human organism.
➡Structure of heart:-
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 tricuspidvalve 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.

heart also known as the pumping centre of the body is the muscular organ that pumps blood through rhythmic contraction and expansion.
-its structure of hear is
-the human heart is divided into 4 chambers
-the upper 2 are called the right and left atrium and the lower 2 as the right and left ventricle
-right atrium receives carbon dioxide rich blood from the body and this blood goes to the right ventricle which contracts and sends this blood to the lungs
-next the oxygen rich blood in return enters at the left atrium from the lungs
-from here the blood enters at the left ventricle
-at last it contacts and pumps away this blood to all the parts of the body.
