Detailed explanation-1: -Ventricles have thicker walls than auricles because they have to pump blood to different organs and the pressure with which the blood flows through them is more than the auricles. Therefore, the walls are thicker in ventricles than in auricles.

Detailed explanation-2: -Left Ventricle. 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-3: -Compared to other blood vessels, arteries have thick walls and are located superficially.

Detailed explanation-4: -The ventricles have thick muscular walls whereas the auricles have thin walls. Why do you think thick muscular walls are necessary in the ventricles and not in the auricles?

Detailed explanation-5: -The left ventricle pumps blood to all parts of the body, while the right ventricle only pumps blood to the lungs. Therefore, the wall of the left ventricle is thicker than the right ventricle.
