Answer:
The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria.
Explanation:
Auricles have thinner walls in comparison to ventricles because the major function of auricles is to receive blood and pump it to the respective ventricles. While the major function of ventricles is pump the blood out of the heart i.e. to lungs and to the body parts which requires a great force.
