The human heart pumps blood throughout the body through the circulatory system, supplying nutrients and oxygen to the tissues and removing carbon dioxide and other wastes. The human heart consists of four chambers:
- Right and Left Atrium
- Right and Left Ventricle
Right and left ventricles are the lower chambers of the heart. Although both the left and right ventricles 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. On the other hand, the left ventricle receives oxygen-rich blood from the left atrium and pumps it to the aorta.
Right Ventricle vs Left Ventricle
Now let us look at the difference between the left and right ventricles given in the tabular column below.
| 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 the pulmonary artery | 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 |
The Left and right ventricles collectively make the apex of the heart. Since the left ventricle wall is thicker than 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.
