Why is the wall of the left ventricle thicker than the wall of the right ventricle? View Available Hint(s) The left ventricle pumps more blood than the right ventricle. The left ventricle pumps blood at a higher pressure than the right ventricle. The left ventricle contracts before the right ventricle does.
