Question

why two ventricles have thicker muscular walls than the two atria in human heart

Answer 1

the two ventricles have thicker muscular walls than the two Atria in human heart because blood is pumped out of the heart at greater pressure from these chambers compared to the atria.

Answer 2

Answer:

Explanation:

Human heart is a soft and four chambered heart having two auricles and two ventricles. These auricles and ventricles are used to carry the blood to different organs of the body.

The auricle is the upper chamber of the heart and the ventricle is the lower chamber of the heart. Two Ventricles have thicker muscular walls than auricles because they have to pump blood to different organs of the body and the pressure with which the blood flows through them is more as compared to the auricles. Therefore, the walls are thicker in two ventricles than in two auricles.
