Difference between the left and right ventricles

What is the Difference between the left and right ventricles? The left and right ventricles are two chambers of the heart which work together to circulate blood. These ventricles store blood prior to its circulation and the main purpose of the left ventricle is to pump blood to the lungs and the right ventricle to the rest of the body.

The main difference – left and right ventricles

Try to understand:

The left ventricle and right ventricle are the two lower passages of the heart. The heart is a muscular organ that pumps blood throughout the body. The upper chamber of the heart is known as the left atrium and the right atrium. The left ventricle receives blood from the left atrium and pumps blood from the aorta to the body. The right ventricle receives blood from the right atrium and sends it out to the pulmonary artery. The left ventricle carries oxygenated blood, and the right ventricle carries deoxygenated blood. The thickness of the wall of the left ventricle is greater than that of the right ventricle. The main difference between the left and right ventricles is that the left ventricle generates greater pressure when pumping blood into the aorta, compared to the left atrium. .

What is the left ventricle?

The left ventricle is the lower left space of the heart and receives oxygenated blood from the left atrium. The left ventricle pumps blood into the aorta. The left and right ventricles form the apex of the heart. The left ventricle is separated from the left atrium by the mitral valve. The left ventricle and aorta are separated by the aortic valve. The aorta supplies oxygenated blood to other parts of the body. The left ventricle consists of the thickest wall of the heart. Therefore, it generates the highest pressure on the blood pumped out into the aorta. The anatomical structure of the heart can be found in Figure 1.

A variety of conditions can affect the structure and function of the left ventricle. Enlargement and hardening of the left ventricle is called left ventricular hypertrophy. It is caused by high blood pressure that cannot be controlled. Myocardial infarction, valvular disease, and myocarditis are some of the other diseases of the left ventricle.

What is the right ventricle?

The right ventricle is the lower right space of the heart that receives deoxygenated blood from the right atrium. The right ventricle supplies blood to the pulmonary artery. The pulmonary artery supplies blood to the lungs. The right ventricle is separated from the right atrium by a tricuspid valve, which prevents the reflux of blood to the right atrium. The pulmonary valve is located between the right ventricle and the pulmonary artery. The thickness of the wall of the right ventricle is thin compared to the thickness of the wall of the left ventricle, so that the right ventricle pumps blood into the pulmonary artery at a lower pressure. The thickness of the walls of the left and right ventricles is shown in Figure 2.

Right side heart failure occurs when the efficiency of blood pumping by the right atrium is low. This condition is called congestive heart failure because the blood can back up or congest. The left and right ventricles are separated from each other by a diaphragm.

Similarities between left and right ventricles

  • Both the left and right ventricles are the lower chambers of the heart.
  • Both the left and right ventricles are composed of the myocardium.
  • Both the left and right ventricles pump blood from the heart.

Differences in the left and right ventricles

definition

Left ventricle: The left ventricle is the left inferior chamber of the heart, which receives oxygenated blood from the left atrium and sends it through the aorta into the body at high pressure.

Right ventricle: The right ventricle is the lower right atrium of the heart, which receives deoxygenated blood from the right atrium and pumps it through the pulmonary artery into the lungs under low pressure.

pressure

Left ventricle: The left ventricle generates more pressure to pump blood into the aorta.

Right ventricle: The right ventricle generates lower pressure than the left ventricle.

Wall thickness

Left ventricle: The left ventricle consists of thick walls.

Right ventricle: The wall of the right ventricle is not thicker than the wall of the left ventricle.

shape

Left ventricle: The left ventricle is oval in shape and forms the apex of the heart.

Right ventricle: The right ventricle has a triangular shape and is located near the apex of the heart.

Receiving Blood

Left ventricle: The left ventricle receives blood from the left atrium.

Right ventricle: The right ventricle receives blood from the right atrium.

Pumping Blood

Left ventricle: The left ventricle pumps blood into the aorta.

Right ventricle: The right ventricle pumps blood into the pulmonary artery.

Types of blood

Left ventricle: The left ventricle carries oxygenated blood.

Right ventricle: The right ventricle carries deoxygenated blood.

blood circulation

Left ventricle: The left ventricle belongs to the systemic circulation.

Right ventricle: The right ventricle belongs to the pulmonary circulation.

disease

Left ventricle: Left ventricular hypertrophy, myocardial infarction, valvular disease, and myocarditis are diseases that can affect the left ventricle.

Right ventricle: congestive heart failure, arrhythmogenic right ventricular dysplasia, and double exit right ventricle is a disease that can affect the right ventricle.

conclusion

The left ventricle and right ventricle are the two lower chambers of the heart that collectively make the apex of the heart. The left ventricle pumps blood into the aorta, and the right ventricle pumps blood into the pulmonary artery. The thickness of the wall of the left ventricle is greater than the thickness of the wall of the right ventricle, so the left ventricle pumps blood at high pressure. The main difference between the left ventricle and the right ventricle is the pressure of the blood pumped out by each ventricle of the heart.
