Ventricles have thicker muscular walls because they need to pump blood with greater force to various organs in the body, whereas atria mainly facilitate blood collection and transfer to the ventricles.

Ventricles have thicker muscular walls because they need to pump blood with greater force to various organs in the body, whereas atria mainly facilitate blood collection and transfer to the ventricles.
The ventricles have thicker muscular walls compared to the atria because they perform different functions in the heart. Atria receive blood from either the body or the lungs and pump it to the ventricles. In contrast, ventricles are responsible for pumping blood out of the heart to either the lungs (right ventricle) or the entire body (left ventricle). The thicker muscular walls of the ventricles enable them to generate greater force during contraction, necessary for pushing blood through the circulatory system. This structural adaptation ensures efficient blood circulation, providing the necessary pressure to propel blood to its destination.
