The Human Heart

The human marrow squash is slightly bigger than the size of ones fist. It is situated at a actually safe place which is between the cage bones, i.e., in the center of the chest. normally it is slightly on the odd side of the chest but in rargon cases, it can be found on the right side. warmness is responsible for the alliance flow to e truly single part of the luggage compartment by constant contraction and relaxation of cardiac muscles.This is the reason wherefore we hear rhythmic beats all the time. burden pumps the pure alliance to the different split of the body and because takes the de group Oated breed from all the move to the lungs for oxygenation. Normally in a minute the summation beats 72 times. Well, lets check out kernel diagram for kids as well as for adults which can help you to sympathize the functioning of heart better.Parts of the tinderAs you can see in the heart diagram, there ar many separate in the heart. So, as we discuss the various parts, you concur checking out the parts simultaneously one by one in the given labeled diagram of the human heart. This will help you to understand the part and their functions more easily.Pericardium Human heart is covered by a double layered structure which is called as pericardium. The outer layer is associated with the study birth vessels whereas the inner layer is attached to the cardiac muscles. These layers ar quarantined by a pericardial fluid. This covering is like a tissue layer which holds all the parts of the heart.Chambers Heart is divided into four put up which are called as left atrium, left ventricle, right atrium and right ventricle. Atrium are the upper chambers of the heart whereas ventricles are the lower chambers of the heart. exclusively these chambers are separated by a tissue layer, called as septum. 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 b ody.Valves There are four valves in the heart namely bicuspid valve, tricuspid valve, pulmonary valve and aortic valve. They help in preventing the back flow of the blood from one chamber to other. This maintains a proper(a) one directional blood flow through out the process. bicuspidate valve is comprise between the left atrium and left ventricle whereas tricuspid valve is present between the right atrium and right ventricle. Pulmonary valve behaves as a furnish which stops the back flow of blood from right ventricle to the pulmonary artery which takes the deoxygenated blood to the lungs for purification. Lastly the aortic valve, this valve plays an important role in stopping the back flow of the blood from left ventricle to the aorta. once the blood is transferred to the aorta it supplies the oxygenated blood to different parts of the body.Blood Vessels Blood vessels are the blood carriers in a human body. These play a very vital role in the supply of blood to various parts of the body. Blood vessels can be of two types, veins and arteries. 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.Functioning of the HeartAfter acquire familiar with the part lets check out the functions of the heart. Well, as we all agnise we need oxygen to survive, but have you ever thought how this oxygen is supplied to different parts of the body? This work is done with the help of heart. Heart plays a very important role in the supply of oxygenated blood in different parts of the body. Deoxygenated blood is collected from various parts of the body and is transferred to heart. The blood enters the heart through the pulmonary valve and enters the right atrium, hence it goes to the right ventricle through the tricuspid valve. From here the blood past goes to the lungs for oxygenation. Oxygenated blood is then brought back to the heart with the help of pulmonary veins and enters the left atrium. The blood then goes to the left ventricle through the bicuspid valve and then transferred to the aorta through the aortic valve for further blood circulation to different parts of the body.
