The atrioventricular valve has four distinct leaflets oriented anterior, posterior, left, and right of the atrioventricular orifice. Hu et al. 2001.[TAO], Valve in the heart through which blood flows from the atria to the ventricles. [TFD][VHOG]
The conus arteriosus is the most distal part of the primitive fish heart and forms the connection between the ventricle and the ventral aorta. At the sinoatrial, the atrioventricular, and the ventriculoconal junctions, valves developed to prevent backflow of blood during relaxation of the preceding compartment.[uncertain][VHOG]
in ZFA this is part of both atrium and ventricle, but we use a connecting relationship here; see also notes for left and right.
