What structure anchors the AV valve to the walls of the ventricles?

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.

Is true the chordae tendineae anchor the semilunar valves to the walls of the ventricles?
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.
Why do auricles have thinner walls than ventricles?
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 walls of ventricles?
Another name for the walls of ventricles is the Purkinje fibers.
What is noticeable about the muscular walls of the atria and the ventricles?
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.
What are the lower two chambers of heart called?
The lower two chambers of the heart are the ventricles. The left ventricle is larger, with thicker walls, than the right ventricle.
Is true the chordae tendineae anchor the semilunar valves to the walls of the ventricles?
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.
How do walls of the artia compare with the walls of the ventricles?
Much thinner.
In longitudinal section how do the walls of the atria and ventricles differ?
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.
Why do auricles have thinner walls than ventricles?
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 walls of ventricles?
Another name for the walls of ventricles is the Purkinje fibers.
What causes the atrio ventricular valves to close?
The rise in pressure inside the ventricles, when the walls of the ventricles contract.
What is heart string?
Hold the valves to inner walls of ventricles
Why have the ventricles got thicker walls then the atria?
atria are just the receiving chambers, it is the ventricles that actually pump the blood into the pulmonary and systemic circuits
Why do arteries able to adjust to the high pressure of the blood when ventricles pump blood?
Because the have thicker walls and sensors in the walls
Functions of the atria?
They have thin walls and they collect blood before it enters the ventricles.
What happens when a persons ventricles have thinner walls then normal?
it breaks more easily
Why are the walls of left ventricles thicker than the walls of right ventricles?
Because the left ventricle pushes blood through most vessels in the body, so it's thicker because more force is needed for the contraction.
