Hey mate!!
FROG belongs to class AMPHIBIA and they have 3-chambered heart, 2 auricles and 1 ventricles (arteriovenous).
Sinus venosus and Truncus Arteriosus are well developed.
FISH belongs to class pisces
° Heart two chambered known as venous heart because it contains only impure blood, which goes to gills for purification from heart, pure blood is then distributed to all parts body directly from gills i.e single circulation of blood
Hope it helps!
