The pelvic veins of both sides are united to form a median ventral or anterior abdominal vein. One ventricle: It is pink colored, conical and lies posteriorly. The separation of the atria allows frogs to keep the oxygenated and deoxygenated blood separate as they come into the heart. chambers. Recent studies show that it is actually completely mixed blood in ventricle and truncus which flows simultaneously through the three pairs of arches to all parts of the body. Auricles aretwo chambered: left and right auricles. This aperture is guarded by two lip like flaps called sinu-auricular valves. Each precaval is formed by the union of 3 major veins which meet simultaneously: It is formed by the slender and sinuous lingual from tongue and mandibular from outer margin of lower jaw. It contains a large cavity called pylangium. The cavity of conus or pylangium is divided incompletely into a left dorsal cavum pulmocutaneum and a right ventral cavum aorticum by a large twisted longitudinal spiral valve. 100+ Horror Collection.
