The left side of the heart, specifically the left ventricle, is the stronger side.
The heart has four chambers: two atria (right and left) and two ventricles (right and left). While both ventricles pump blood, the left ventricle has a more demanding job.
- Right Ventricle: Pumps blood a short distance to the lungs for oxygenation. This requires less force.
- Left Ventricle: Pumps blood to the entire body, including the brain, organs, and limbs. This requires significantly more force to overcome the systemic resistance and ensure adequate blood flow throughout the body.
Because of this greater workload, the left ventricle has thicker, more muscular walls than the right ventricle. This allows it to generate the higher pressure needed to circulate blood throughout the body. The left ventricle is therefore considered the strongest of the heart's chambers.
