Detailed explanation-1: -Ventricles have thicker walls than auricles because they have to pump blood to different organs and the pressure with which the blood flows through them is more than the auricles. Therefore, the walls are thicker in ventricles than in auricles.
Detailed explanation-2: -The two atria are thin-walled chambers that receive blood from the veins. The two ventricles are thick-walled chambers that forcefully pump blood out of the heart.
Detailed explanation-3: -Solution : It is because auricles have to pump blood to ventricles which are lying below them and ventricles have to pump to all parts of the body.
Detailed explanation-4: -The heart cavity is divided down the middle into a right and a left heart, which in turn are subdivided into two chambers. The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle.
