Final answer:
The atrioventricular valves are the tricuspid valve, located between the right atrium and right ventricle, and the mitral (bicuspid) valve, found between the left atrium and left ventricle. They ensure one-way blood flow from the atria to the ventricles.
Step-by-step explanation:
The names of the atrioventricular valves are 1) Tricuspid and Bicuspid (also known as the Mitral valve). The atrioventricular valves are essential one-way valves located between the atria and ventricles of the heart. Specifically, the tricuspid valve is situated at the opening between the right atrium and the right ventricle. On the other side, the mitral or bicuspid valve is located at the opening between the left atrium and the left ventricle. The mitral valve is often referred to clinically as the mitral rather than the bicuspid valve, despite having two cusps (the anterior medial cusp and the posterior medial cusp) attached to papillary muscles via the chordae tendineae. These valves play a crucial role in maintaining one-way blood flow through the heart, from the atria to the ventricles, preventing backflow.
