Detailed explanation-1: -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.
Detailed explanation-2: -The left ventricle is the thickest of the heart’s chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
Detailed explanation-3: -The two lower chambers, the ventricles, are larger, thick-walled chambers that pump the blood to all parts of the body. The septum is a muscular wall that divides the right atrium from the left atrium and the right ventricle from the left ventricle.
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.
