Answer 2

Answer:

Their muscular walls are thicker than the atria because they have to pump blood out of the heart. ... This is because the left ventricle has to pump blood at a higher pressure so that it reaches all areas of the body (including the fingers and toes) but the right side only has to pump blood to the lungs.
