Importance Of Chambers Of Human Heart

We have so many organs present in our human body all of whom have different essential functions to perform. Humans can survive without any organ even if the brain which is the control unit of the human body is not working a human can still survive without consciousness. But one organ without the function of which survival is not possible is the 'Human Heart'. The heart's blood throughout the body carries oxygen and nutrients to every cell. It is this circulation of blood that is vital to sustaining life. The human heart is an important organ made up of a tough layer of muscle that covers the exterior of the heart and protects the inside walls.

The working of the human heart is achieved by the division of the heart into four Chambers. The Heart can't work without these divisions which display the 'Importance of Chamber of Human Heart'. The heart was in the upper two-layer chamber known as Atrium which received blood coming into the heart. While it also has a ventricle that pumps blood out of the heart. The upper chamber has comparatively weaker walls than the lower chamber because they receive the blood from the body, unlike the lower chamber which requires thicker muscle to pump out blood with force to ensure that supply of blood to it whole body in the upper direction against Gravity.

Between each chamber are valves that open and close and help to separate oxygenated and deoxygenated blood. The valve present between the right atrium and right ventricle is called "Tricuspid Valve" while between the left atrium and left ventricle is called " Mitral Valve". However, the valve between the right ventricle and pulmonary artery is called the "Pulmonary valve" while between the left ventricle and Aorta is called the "Aorta valve". When the atrium contract the blood move downwards with the opening of the Tricuspid and Mitral valves respectively. And when it comes to the ventricles, the blood moves upwards during their contraction with the opening of the Pulmonary and Aortic valves.

Hence, the pumping starts with the rhythmic contractions and relaxation of chambers with the opening and closing of valves to ensure proper circulation of blood throughout the body.
