Left Ventricle vs. Right Ventricle: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 13, 2023
Left ventricle pumps oxygenated blood to the body; right ventricle pumps deoxygenated blood to the lungs. Both are chambers in the heart with different circulatory roles.

Key Differences

The left ventricle and right ventricle are integral components of the heart’s anatomy. Each ventricle performs a distinct role within the circulatory system, optimizing oxygen transport and blood circulation. The left ventricle propels oxygen-rich blood into systemic circulation, while the right ventricle is tasked with moving oxygen-depleted blood toward the lungs.

Physically, the left ventricle is typically more muscular and thicker-walled than the right ventricle. This robust structure supports its duty to pump blood throughout the entire body, necessitating a higher pressure and force. The right ventricle, conversely, has a thinner wall, as it only needs to push blood a short distance to the lungs, requiring less force.

Considering blood circulation, the left ventricle sends blood into the aorta, from where it circulates to various body parts, providing them with essential oxygen and nutrients. Conversely, the right ventricle directs blood into the pulmonary artery, channeling it towards the lungs where it is to be oxygenated, highlighting their distinct roles in systemic and pulmonary circulation, respectively.

Various conditions can affect the left and right ventricles differently. For instance, left ventricular hypertrophy involves the thickening of the left ventricle’s muscular wall, often resulting from high blood pressure or other cardiac conditions. The right ventricle, however, may be more directly involved in conditions like pulmonary hypertension, which originates from increased pressure within the pulmonary artery.

Despite their differences, the left ventricle and right ventricle work in harmonious synchronization within the cardiac cycle. As the left ventricle delivers oxygenated blood to the body, it fuels the organs and systems that maintain life. Simultaneously, the right ventricle ensures that deoxygenated blood reaches the lungs, where it can be refreshed with oxygen, perpetuating the vital cycle.

Left Ventricle and Right Ventricle Definitions

Left Ventricle

The left ventricle sends oxygen-rich blood to the body.
Oxygenated blood is propelled by the left ventricle to nourish various tissues.

Right Ventricle

The right ventricle receives deoxygenated blood from the right atrium above it.
Blood flows from the right atrium into the right ventricle, following the tricuspid valve’s opening.

Left Ventricle

The left ventricle is the heart's lower left chamber.
Blood exits the left ventricle into the aorta.

Right Ventricle

The right ventricle is one of the heart’s four chambers, located in the lower right section.
The right ventricle pushes deoxygenated blood toward the lungs.

Left Ventricle

The left ventricle receives blood from the left atrium.
Oxygenated blood flows from the left atrium to the left ventricle before being distributed to the body.

Right Ventricle

It plays a crucial role in the pulmonary circulation by transporting deoxygenated blood.
The right ventricle ensures that blood lacking oxygen reaches the lungs for oxygenation.

Left Ventricle

It has thicker walls than the right ventricle to pump blood forcefully.
The left ventricle needs to exert more pressure to circulate blood throughout the body.

Oct 13, 2023

Right Ventricle

It directs blood into the pulmonary artery to convey it to the lungs.
The right ventricle propels blood through the pulmonary valve into the pulmonary artery.

Left Ventricle

Left ventricular hypertrophy is a condition involving thickening of its walls.
Left ventricular hypertrophy often signals prolonged high blood pressure.

Oct 13, 2023

Right Ventricle

This chamber has thinner walls than the left ventricle since it pumps blood a shorter distance.
Despite its thinner walls, the right ventricle efficiently moves blood to the nearby lungs.
