Question

give reasons why Ventricles have thicker muscular wall than atria.

Answer 1

Hey
Here is your 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. The left ventricle also has a thicker muscular wall than the right ventricle

Answer 2

Yes because arteries carry blood at high pressure so they require thicker walls and walls of arteries are more thicker because the heart contracts and push the blood at which pressure.Thicker walls prevent arteries from bursting
