[Review question: Pg. No: 84]

Answer 1

1. The ventricles of the heart have thicker muscular walls than the atria.
2. The left ventricle also has a thicker muscular wall than the right ventricle.
3. This is due to the higher forces needed to pump blood through the systemic circuit compared to the pulmonary circuit.
