Human Heart Diagram Class 10th

Human Heart

Human Heart is a muscular organ located in the chest between the lungs. It is about the size of a fist and is responsible for pumping blood throughout the body. It has four chambers – The right atrium, Right ventricle, Left atrium and Left ventricle.

Human Heart Diagram

Description of Human Heart Diagram labels is as follows-

Aorta

Aorta is the main blood vessel of the body that carries oxygenated blood from the heart to the rest of the body.

Superior Vena Cava 

Superior Vena Cava is a large vein that carries deoxygenated blood from the upper body back to the heart.

Inferior Vena Cava

Inferior Vena Cava is the large vein that carries deoxygenated blood from the lower body back to the heart.

Pulmonary artery

 Pulmonary Artery is the Blood Vessel  that carries deoxygenated blood from the right ventricle to the lungs for oxygenation.

Pulmonary veins

Pulmonary Vein is the blood vessel that carries oxygenated blood from the lungs back to the left atrium.

ALso Check- Types and Functions of Blood Vessels

Left atrium

Left Atrium is the upper chamber on the left side of the heart that receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle.

Mitral Valve (Bicuspid Valve) 

Mitral valve / Bicuspid Valve valve is located between the left atrium and the left ventricle. It controls the flow of oxygen-rich blood from the left atrium to the left ventricle.

Aortic Valve

Aortic Valve is the valve located between the left ventricle and the aorta. The aortic valve controls the flow of blood from the left ventricle into the Aorta.

Tricuspid Valve

Tricuspid Valve is located between the right atrium and the right ventricle. It controls the flow of blood from the right atrium to the right ventricle.

Pulmonary Valve

Pulmonary Valve valve is located between the right ventricle and the pulmonary artery, which carries oxygen-poor blood to the lungs for oxygenation. Pulmonary valve controls the flow of blood from the right ventricle into the pulmonary artery.

Septum

The right and left sides of the heart are divided by this wall of muscle.

Left ventricle

Oxygen-rich blood travels from this chamber to the Aorta.

Right ventricle

Right Ventricle is the lower chamber on the right side of the heart that pumps deoxygenated blood to the lungs for oxygenation.

Right atrium

Right Atrium is the upper chamber on the right side of the heart that receives deoxygenated blood from the vena cava and pumps it into the right ventricle.
