Which valves are located between the atria and ventricles in the heart?

The atrioventricular valves are specifically designed to separate the atria from the ventricles in the heart. There are two atrioventricular valves: the tricuspid valve, which is located between the right atrium and the right ventricle, and the mitral (or bicuspid) valve, which is found between the left atrium and the left ventricle. These valves play a crucial role in ensuring that blood flows in one direction—allowing it to move from the atria to the ventricles while preventing backflow during ventricular contraction.

In contrast, the semilunar valves, which include the pulmonary and aortic valves, are located between the ventricles and the major arteries (pulmonary artery and aorta, respectively). They primarily function during the ejection of blood from the heart to prevent backflow into the ventricles. The tricuspid valve is indeed one of the components of the atrioventricular valves, but it is not the complete answer to the question, which encompasses both atrioventricular valves as a group. The pulmonary valves are specifically related to the outflow from the right ventricle to the pulmonary artery and do not serve a role in separating the atria from the ventric
