• 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.
