Explain why there is a difference in thickness of the walls​

The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as seen in the adjacent image.

I assume you are talking about the heart. If you are not talking about the heart, let me know and I will come back and edit this answer.

Explanation:

The heart is a strong siphon that courses blood through veins by musically contracting and unwinding. The heart sits in a pit behind the sternum (breastbone). The normal grown-up heart is around 12cm long through and through.

The heart is comprised of four chambers, two on the right and two on the left. Despite the fact that they work on schedule with one another, the different sides are isolated by a strong divider called the septum.

The upper chambers are the right and left atria. Their muscle dividers are slim and flexible, and they gather blood coming into the heart.

The lower chambers are the right and left ventricles, which get blood from the atria above. Their strong dividers are thicker than the atria since they need to siphon blood out of the heart. Albeit the left and right ventricle are comparative in structure, the dividers of the left ventricle are thicker and more grounded. This is on the grounds that the left ventricle needs to siphon blood at a higher pressing factor so it arrives at all spaces of the body (counting the fingers and toes) however the right side just needs to siphon blood to the lungs. This implies that the heart isn't exactly balanced.

The two chambers on the right get blood from the body and siphon it to the lungs, where it gets oxygen. The two on the left get the blood from the lungs, recently loaded up with oxygen, and siphon it out to the body, where the oxygen is spent.

The heart needs an inventory of oxygen and glucose to work. This is given by blood conveyed to the heart by coronary supply routes which lie on the external surface of the heart, and away from the heart via cardiovascular veins.
