Question

The muscular walls of ventricles are thicker than the walls of atria

Answer 1

Answer:

the ventricles of the heart have thicker muscular wall than atria because blood is pumped out of the heart at greater pressure from this chamber compared to the atria the ventricle have also muscular wall than the right ventricle

Answer 2

The Heart is divided into four chambers namely two upper Atria and two lower Ventricle.

The atria have comparatively thinner walls than the ventricles because atria only receive blood from the upper parts of the body,i.e., head, etc. and the ventricles have to pump the blood to the farthermost parts of the body, for example, the toes to up to head,i.e., against gravity.
