10 ELEMENTARY PHYSIOLOGY. [l. 



duct passing downwards from each kidney over 

 the muscles of the back towards the middle line; 

 trace them to their entrance into the urinary 

 bladder. 



25. Trace out the renal artery and vein noted in 9, 

 follow them into the substance of the kidney. 

 Divide one kidney longitudinally, note the single 

 pyramid opening into the pelvis. 



26. In dissecting a female rabbit, observe the uterus, 

 with its two cornua, from each cornu proceeds a 

 Fallopian tube which taking a winding course 

 upwards for some little distance ends in a clump 

 of processes or fimbrise. Near the end of each 

 Fallopian tube a little below the kidney will be 

 seen a small, ovoid spotted body, the ovary. 



27. In dissecting a male rabbit, observe in each side 

 of the lower part of the abdominal cavity a white 

 convoluted tube the vas deferens. Cut through 

 the symphysis pubis with bone forceps, stretch 

 the halves apart and cut away as much bone on 

 each side as may be necessary. Trace the vasa 

 deferentia downwards cutting open the scrotal 

 sacs; each vas deferens is continuous with a 

 coiled mass of tubes, the epididymis, attached 

 to one side of the testis. Note that the smooth 

 membrane, tunica vaginalis, lining the scrotal 

 sacs is continuous with the peritoneum. 



28. Lay open the bladder, observe its neck ending in 

 the urethra, note the openings of the ureters into 

 the dorsal part of the bladder and in the male 

 the openings of the vasa deferentia near its neck.
