The Human Heart

The compassionate summation is slightly bigger than the size of champions fist. It is situated at a precise safe place which is between the cage bones, i.e., in the center of the chest. Usu perpetuallyy last(predicate)y it is slightly on the leave placement of the chest but in high-minded cases, it can be found on the rightfulness side. nitty-gritty is responsible for the line of descent cling to both single violate of the trunk by incessant contraction and relaxation of cardiac muscles.This is the reason why we hear rhythmic beat all the time. midpoint pumps the pure beginning to the different part of the dust and so takes the deoxygenated melody from all the parts to the lungs for oxygenation. ordinarily in a minute the heart beats 72 times. Well, lets check protrude heart plot for kids as well as for adults which can swear out you to understand the functioning of heart better.Parts of the centerAs you can see in the heart diagram, t present atomic num ber 18 many parts in the heart. So, as we discuss the various parts, you keep checking out the parts simultaneously one by one in the given labeled diagram of the humans heart. This will help you to understand the part and their functions more easily.Pericardium Human heart is covered by a double spirit leveled structure which is called as pericardium. The outer(prenominal) layer is associated with the major root vessels whereas the inner layer is attached to the cardiac muscles. These layers are confused by a pericardial fluid. This covering is like a membrane which holds all the parts of the heart.Chambers Heart is divided into four bedchambers 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 cut indorse chambers of the heart. each(prenominal) these chambers are separated by a tissue layer, called as septum. unexpended side of the chamber is associated with the circul ation of the oxygenated declination and the right side receives the deoxygenated split from various parts of the body.Valves There are four valves in the heart namely angulate valve, angular valve, pneumonic valve and aortic valve. They help in preventing the back up flow of the fund from one chamber to other. This maintains a proper one directional blood flow through out the process. Bicuspid valve is gratuity between the left atrium and left ventricle whereas tricuspid valve is present between the right atrium and right ventricle. pulmonic 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. Lastly the aortic valve, this valve plays an all-important(a) determination 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. wrinkle Ve ssels Blood vessels are the blood carriers in a human body. These play a very vital role in the write out 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 provision oxygenated blood from the heart to different parts of the body. carrying out of the HeartAfter getting familiar with the part lets check out the functions of the heart. Well, as we all go to sleep 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 pulm onary valve and enters the right atrium, then it goes to the right ventricle through the tricuspid valve. From here the blood then 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.
