Question

I need an answer asap thanks
Why do you think that:
A. The walls of the ventricles are more muscular than the walls of the atria.
B. The muscle of the left ventricle is thicker than that of the right ventricle?

Answer 1

because the blood pressure in ventricals are lower than atria

the muscle is thicker because the blood enters through the left and to maintain this pressure the lrft wall is thicker
