Question

ventrcles are thick walls?why​

Answer 1

Hi my dear friend,

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. ... This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.

~Thank you

Answer 2

Ventricles are thich walled as blood is pumped with a great pressure from auricle. In this case if ventricle is thin walled the blood will escape  by that pressure by tearing that muscles
