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]
