Question

ventricles have thicker walls than auricles​

Answer 1

Answer:

ventricles have thicker walls than auricles because the blood in the ventricles is pumped with a higher pressure than in auricles

Answer 2

Answer:

Ventricles have to pump the blood to whole body whereas auricles have to pump the blood to ventricles only So ventricles need to create more pressure to pump the blood to large distance whereas auricles only pump blood to small distance.
