right ventricle

left ventricle

Detailed explanation-1: -The left ventricle has the thickest wall out of all the chambers. The left ventricle is responsible for pumping the blood towards the tissues of the heart. This is why more muscles contracting inside the left ventricle helps produce a higher force to move the blood towards the system.
Detailed explanation-2: -The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about 1.0 to 1.3cm, but they have enough force to push blood through the aortic valve and into your body.
Detailed explanation-3: -The left ventricle is the strongest because it has to pump blood out to the entire body. When your heart functions normally, all four chambers work together in a continuous and coordinated effort to keep oxygen-rich blood circulating throughout your body.
Detailed explanation-4: -The left ventricle is the main powerhouse of the heart, having to pump blood all the way around the systemic circulation. Because of this it has the largest, most muscular walls of any of the chambers. In fact, it is three times as thick as the right ventricle.
Detailed explanation-5: -Ventricles have thicker walls than the auricles as it has to pump the blood to all parts. Since it has to pump oxygenated blood to all the parts of the body, left ventricle present in the heart has the thickest wall.
