Question

Give reason-the two ventricles have thicker muscular walls than the two etria in human heart?<br /><br />please answer fast<br />Important!!!!!!!!

Answer 1

the venticles have thicker walls than the atria because they have to pump blood to the whole body with pressure and if they had thin walls then during high pressure contraction they would have got damaged . Therefore they have thicker walls

Answer 2

$\huge\mathcal{\blue {\underline {\overline {\mid {\purple {Answer}}\mid}}}}$

• 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.
