Difference Between Left And Right Ventricle

Difference Between Left And Right Ventricle

We know that the human heart is an organ that pumps blood throughout the body through the circulatory system supplying nutrients and oxygen to the tissues removing carbon dioxide and other wastes. The human heart consists of four chambers as follows:

  • Right and Left Atrium
  • Right and Left Ventricle

Right and left ventricle constitute the lower chambers of the heart. Although both left and right ventricle belong to the lower chambers, they both differ in their functionalities. The right ventricle receives the deoxygenated blood from the right atrium and pumps it to the pulmonary artery. The left ventricle, on the other hand, receives oxygen-rich blood from the left atrium and pumps it to the aorta. Now let us look at the difference between left and right ventricle given in the tabular column below.

Right vs Left Ventricle

Right Ventricle Left Ventricle
Receives deoxygenated blood from the right atrium Receives oxygen-rich blood from the left atrium
Comprises a thin wall Comprises a thick wall
Pumps the received blood to the lungs through pulmonary trunk Pumps the received blood to the whole body through the aorta
The cavity is crescentic in shape The cavity is circular in shape
Develops a lower pressure than the left ventricle while pumping blood Develops higher pressure while pumping blood
Triangular in shape and is near the apex of the heart Oval in shape and forms the apex of the heart

Left and right ventricle collectively make the apex of the heart. Since the wall of the left ventricle is thicker than that of the right ventricle, the left ventricle pumps blood with high pressure. The main difference between the right and the left ventricle is the pressure of the blood pumped by each ventricle.
