Solution
The correct option is A Oliver
The frog has a three-chambered heart and consists of a conical ventricle and two auricles which lie immediately in front of the ventricle. While the auricles are thin walled and separated internally by a septum, these are clearly separated from the ventricle by a coronary suculus. The Truncus arteriosus lies on the front side of the ventricle and are divisible into two visible parts. Ms. Oliver (1909 ) was the first to call the entire vessel as truncus arteriosus and divided its interior into proximal pylangium and a distal synangium.
