Fig. 400.—Diagrams of the urinary and generative organs of the frog. A, Organs of the male ; B, those of the female ; bladder ; c/., cloaca ; , egg sac; , fat body; , internal opening of oviduct; k., kidney; ', kid- ney duct (Wolffian duct); od., oviduct; ov'.t ovary; , suprarenal body; t., testis ; , vasa efFerentia ; , vesicula seminalis. The heart will sometimes be beating when the body is opened, though the animal is dead. If not, it may often be stimulated to beat by a prick. In the beating heart, note the successive phases of the beat (p. 54). lb. Turn the heart back, cut through one superior vena cava, and remove its branches. Wash the dissection. Note ; auricles, ventricle, truncus. Trace: carotid, systemic, and pulmonary arches; lingual artery, carotid gland, and common carotid artery; subclavian and cceliaco-mesenteric arteries ; dorsal aorta (Fig. 30). 80. Remove the kidneys and generative organs without injuring the aorta. Note: vertebral column; dorsal aorta and.
