Question

the walls of ventricles thicker than the auricels why

Answer 1

this is because blood is pumped out of the heart at great pressure from these chambers compared to auricle.

Answer 2

Because left ventricle pumps out blood to different parts of body so it is easy to pump blood because its wall is thick(pressure is inversely proportional to area). Right ventricle has a lower pressure than the left ventricle because the right only has to get blood to lungs. Left side pumps to whole body. Also auricles needs much less pressure because they just pump blood to next ventricle. Hope you like my answer. If you like my answer then please brainliest it.
