Question

explain the working of heart with a help of a diagram.

Answer 1

Blood is pumped from the right atrium down into the right ventricle and from the left atrium down into the left ventricle. In the second stage, the lower chambers contract to push this blood out of the heart to either the body via your main artery (aorta) or to the lungs to pick up oxygen

Answer 2

Human heart is slightly bigger than the size of one's fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. It is slightly on the left side of the chest but in rare cases, it can be found on the right side. Heart is responsible for the blood flow to every single part of the body through constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps pure blood to different parts of the body and then takes the deoxygenated blood from all the parts to the lungs for oxygenation. Normally in a minute the heart beats 72 times and pumps around 1,500 to 2,000 gallons of blood per day. Let's check out heart diagram which can help you to understand functioning of the heart in a better way.
