A faulty conus arteriosus would compromise on an effective gaseous exchange that keeps the blood of the
fish oxygenated for respiration of
tissues. The conus arteriosus is one of two accessory chambers found in most
fish with two-chambered hearts. The primary function of the conus arteriosus is
to prevent the backflow of blood and keep a steady flow of blood into the
ventral aorta and the gills.
