Functioning of the HeartĪfter getting familiar with the different parts, let’s check out various functions of the heart. All the veins (except pulmonary vein) are involved in carrying the deoxygenated blood from various parts of the body to the heart whereas all the arteries (except pulmonary artery) are involved in supplying oxygenated blood from the heart to different parts of the body. Blood vessels can be of two types, veins and arteries. These play a very vital role in the supply of blood to various parts of the body. Once the blood is transferred to the aorta it supplies the oxygenated blood to different parts of the body.īlood vessels are the blood carriers in a human body. Lastly the aortic valve, this valve plays an important role in stopping the back flow of the blood from left ventricle to the aorta. Pulmonary valve behaves as a gate which stops the back flow of blood from right ventricle to the pulmonary artery which takes the deoxygenated blood to the lungs for purification. Bicuspid valve is present between the left atrium and left ventricle whereas tricuspid valve is present between the right atrium and right ventricle. This maintains a proper one directional blood flow throughout the process. They help in preventing the back flow of the blood from one chamber to other. There are four valves in the heart namely bicuspid valve, tricuspid valve, pulmonary valve and aortic valve. Left side of the chamber is associated with the circulation of the oxygenated blood and the right side receives the deoxygenated blood from various parts of the body. All these chambers are separated by a layer of tissues known as septum. Atriums are the upper chambers of the heart, whereas ventricles are the lower chambers of the heart. Heart is divided into four chambers, left atrium, left ventricle, right atrium and right ventricle. Let’s check out heart diagram which can help you to understand functioning of the heart in a better way. Normally in a minute the heart beats 72 times and pumps around 1,500 to 2,000 gallons of blood per day. 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. This is the reason why we hear rhythmic beats all the time. Heart is responsible for the blood flow to every single part of the body through constant contraction and relaxation of cardiac muscles. It is slightly on the left side of the chest but in rare cases, it can be found on the right side. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. Human heart is slightly bigger than the size of one’s fist. This diagram of the heart will not only give you details about the various parts, but will also explain the importance of keeping your heart healthy. In this article, we are going to discuss various functions of heart with the help of a well labeled diagram. In this working, heart holds a very important place. All major organs of the body like brain, heart, stomach, kidney, liver, etc., work in coordination to sustain one’s life smoothly. Every single part of our body is so well designed, that it works continuously throughout our life. The human body is the best machine created by God.
