Chondrichthyans have a bulbus arteriosus at the arterial pole of the heart: morphological and evolutionary implications



Chondrichthyans have a bulbus arteriosus at the arterial pole of the heart: morphological and evolutionary implications



Journal of Anatomy 213(5): 597-606



It has been generally assumed that the outflow tract of the chondrichthyan heart consists of the conus arteriosus, characterized by cardiac muscle in its walls. However, classical observations, neglected for many years, indicated that the distal component of the cardiac outflow tract of several elasmobranch species was composed of tissue resembling that of the ventral aorta.
