Question

the muscular walls of ventricle are thicker than the wall of atria .give reason​

Answer 1

Answer:

Explanation:

Muscular walls of ventricle are thicker than atria because they have to pump blood farther so they need a great force to pump which would be provided by the thick muscles.

Left ventricle pumps oxygenated blood to all parts of body through aorta.

Right ventricle have to pump deoxygenated blood to lungs for gaseous exchange.

Answer 2

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