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.

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 myocardium is the middle layer of the heart. It is the heart muscle and is the thickest layer of the heart.

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.
