Where are a-v valves located?

A-V valves, or atrioventricular valves, are located between the atria and ventricles of the heart. Specifically, the tricuspid valve is situated between the right atrium and right ventricle, while the mitral (or bicuspid) valve is found between the left atrium and left ventricle. These valves play a crucial role in ensuring unidirectional blood flow through the heart.
