The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles), according to the National Institutes of Health. The right atrium and right ventricle together make up the "right heart," and the left atrium and left ventricle make up the "left heart." A wall of muscle called the septum separates the two sides of the heart.

A double-walled sac called the pericardium encases the heart, which serves to protect the heart and anchor it inside the chest. Between the outer layer, the parietal pericardium, and the inner layer, the serous pericardium, runs pericardial fluid, which lubricates the heart during contractions and movements of the lungs and diaphragm.

The heart's outer wall consists of three layers. The outermost wall layer, or epicardium, is the inner wall of the pericardium.  The middle layer, or myocardium, contains the muscle that contracts. The inner layer, or endocardium, is the lining that contacts the blood.

The tricuspid valve and the mitral valve make up the atrioventricular (AV) valves, which connect the atria and the ventricles. The pulmonary semi-lunar valve separates the right ventricle from the pulmonary artery, and the aortic valve separates the left ventricle from the aorta. The heartstrings, or chordae tendinae, anchor the valves to heart muscles.

HUMAN HEART :

》Human Heart is mesodermal in origin.

》It is located in the thoracic cavity between the lungs.

》It is protected by pericardium which is a double walled membrane enclosing pericardial fluid.

》Our heart consists of four chambers - two upper chambers called atria and two lower chambers called ventricles.

》A thick walled septum called the inter-ventricular septum separates the left and right ventricles.

》A thin septum called inter-atrial septum separates right and left atria.

》Atrioventricular septum separates the atria and the ventricle of the same side.

》Bicuspid Valve regulates the opening between the left atrium and left ventricle.

》The opening between the right atrium and right ventricle is regulated by Tricuspid Valve.

FUNCTION :

● The function of Heart is to pump oxygenated blood to all the parts of our body and also to pump the deoxygenated blood from lungs to heart.
