What is the Function of the tissue between the atria and ventricles?

The tissue between the atria and ventricles are mainly valves (tricuspid valve between the right A and right V, and the bicuspid/mitral valve between the left A and left V).
The function of these valves is to prevent backflow of blood (back into the atria), when the muscles (papillary muscles) attached to the valves contract following diastole (which is the relaxation of the heart -simply put-).
When these valves close, systole (which is the contraction of the ventricles) occurs. If the valves are not shut during systole all the blood will not be guided towards the big vessels (pulmonary artery in the case of the right ventricle, and the aorta in the case of the left ventricle) as they are supposed to. Instead some blood will "regurgitate", meaning that it will flow back into the atrium where it came from. This regurgitation is a leading cause of congestive heart failure.

Function of atria?
ventricles
Flaps of connective tissue called valves are located between the atria and the ventricles?
TRUE
What is the main function of the right atria left atria?
to force blood to the ventricles
What difference atria and ventricles fetal pig?
the difference between the ventricles and the atria is that the ventricles are thicker
What makes the valves between atriums open and close?
There are no valves between the atria. The valves between the atria and ventricles close when the ventricles contract.
What differences between the atria and the ventricles?
-the atriums are smaller then the ventricles. -the atriums have thinner muscle tissue. -the atriums only have to pump blod to the ventricles. -the ventricles are larger in size. -the ventricles have larger muscle tissue. -the ventricles have to pump blood to either the lungs or around to the rest of the body. hope this helpedddd ;D xox <3 Bellaaaa
When atria relax ventricles do what?
When relaxed, the atria expand, and then the ventricles contract.
What two components of the conduction system constitute the only electrical link between the atria and the ventricles?
The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.
Is the function of the atria?
Its main function is to receive the blood that will then be pumped throughout the ventricles as well as the rest of the body.
Why is the atria so thin walled?
Atria don't do nearly the same amount of work of contraction as do the ventricles. They are therefore relatively thin walled. Most of the blood that flows from the atria to the ventricles flows passively, and so the atria function mostly as a reservoir for blood volume.

Do atria contract before the ventricles?
Yes, atria contracts before the ventricles.
