Question

why are the walls of ventricles thicker than the aricles​

Answer 1

Answer:

Since ventricles have to pump blood to different body parts, the blood exerts pressure on the walls of ventricles .Hence, the walls of ventricles are thicker than that of atrium to protect against the pressure of pumping and pressure of blood flow.

Explanation:

Answer 2

Answer:

Blood flows under high pressure through ventricles.

Explanation:

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.
