The atrio-ventricular valves (or A-V valves) are exactly what their name implies. They are valves located between the atria and ventricles. Since there are two atria and two ventricles, it follows naturally that there must be two A-V valves. The one on the right is called the TRICUSPID valve and the one on the left is called the MITRAL valve.
By strands of chordae tendonae to the muscles of the ventricle
Papillary muscle
No. in my opinion, Chordae tendineae is attached to Tricuspid valve and bicuspid valve. Both valves do not have semilunar valves. Pulmonary valve and Aortic valve has semilunar valve.
Ventricles have thicker valve thicker wall so that they can withstand the intense pressure by the heart.While auricles carry blood towards the heart and suffers reduced pressure so it has thinner wall
Another name for the walls of ventricles is the Purkinje fibers.
The walls of the left ventricle are thicker due to having to pump the blood to the body. The walls of the right ventricle are thinner because blood is being pumped into the lungs for gas exchange.
The lower two chambers of the heart are the ventricles. The left ventricle is larger, with thicker walls, than the right ventricle.

Much thinner.
In longitudinal section, the walls of the atria are thinner, and lined with pestinate muscles. The walls of the ventricles, meanwhile, are thick and muscular.

Another name for the walls of ventricles is the Purkinje fibers.
The rise in pressure inside the ventricles, when the walls of the ventricles contract.
Hold the valves to inner walls of ventricles
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
Because the have thicker walls and sensors in the walls
They have thin walls and they collect blood before it enters the ventricles.
it breaks more easily
Because the left ventricle pushes blood through most vessels in the body, so it's thicker because more force is needed for the contraction.
