Hello Students, Here we are provided Labelled diagram of Schematic sectional view of the human heart with pencil in a simple way. Drawing of Schematic sectional view of the human heart can be huge struggle for beginners. CBSE / ICSE students who are always avoid drawing, this post is just for you!

Heart is a muscular organ which is function to pump the blood of the body. The normal size of human heart is almost once fist. Human heart is mainly divided into 4 chambers, for the separation of oxygenated and deoxygenated blood. Chambers are functioned as, both types of blood – oxygen rich blood and carbon dioxide containing blood should not mix with each other. All the four chambers are provided with valves or septum (dividing wall) to prevent the back flow of the blood. Heart is the pumping organ of the blood which is important to impel the blood with force so that the blood should reach to each part and every tissue of the body.

The process of the transportation of blood from the human heart is as follows – 

There are 2 vena-cavas present in the heart namely superior venacava and inferior venacava.

Superior venacava carries deoxygenated blood from the upper body and inferior venacava Carries deoxygenated blood from lower body. Both the venacavas pour the blood into right atrium. When right atrium contracts the blood goes into right ventricle. As soon as blood is poured into right atrium it contracts and the blood is pumped into pulmonary arteries which goes towards the lungs. Lungs perform the function of removing carbon dioxide from the deoxygenated blood and the oxygenated blood which is purified by the lungs is bring back towards the heart by the pulmonary veins. The oxygenated blood brought by the pulmonary veins is poured into left atrium. When left atrium contacts the blood is poured into left ventricle. From the left ventricle the oxygenated blood is pumped into aorta . This aorta then divided into many arteries and transport the oxygen rich blood to each and every part of the body. The arteries has to transport and pump the blood with force to each and every organ the walls of the arteries are thick and muscular.
