The right ventricle has to pump blood out of the heart and through the lungs, to return it to the left atrium. There is a lot of resistance to blood flow through the lung capillaries, so a thick musle wall is needed to generate enough pressure to overcome this resistance. The right atrium only has to pump blood through an open valve (the tricuspid valve) into the right ventricle. There is much less resistance to this flow of blood so much less muscle is needed.

What are the 4 chambers of the heart?
Right Atrium , Left Atrium , Right Ventricle , Left Ventricle
What are the four chambers of the heart are called?
The four chambers are; Left atrium Right atrium Left Ventricle Right Ventricle The two upper chambers are called atria (singular: atrium) and the two lower chambers are called ventricles. There are four chambers of the heart - the right atrium, left atrium, right ventricle and left ventricle.
Which ventricle is that muscle layer thinner and thicker?
The muscle layer of the heart, known as the myocardium, is thicker in the left ventricle compared to the right ventricle. This is because the left ventricle pumps oxygenated blood to the entire body, requiring more force and thicker muscular walls. In contrast, the right ventricle pumps deoxygenated blood only to the lungs, necessitating a thinner muscle layer.
What does the right atrium connect too?
The right Atrium connects to the right ventricle.
Are the thickest walls in the right atrium?
No, the thickest walls of the heart are found in the left ventricle, not the right atrium. The left ventricle has thicker walls because it has to pump blood to the entire body, requiring more muscular strength. In contrast, the right atrium has relatively thin walls, as it only receives blood from the body and pumps it into the right ventricle.
