288 THE RABBIT 



The urinary system is the same in both sexes, except that in the female the 

 ureters open into the bladder near its front end. 

 B. The Reproductive System. 



{a) The Male. 



The scrotal s&cs, two pouches of the abdominal wall, communicate with the 

 abdomen through the narrow inguinal canal (the neck of the scrotal sac).

Fig. 95. — The Rabbit (Lepus cnniculua). The veins and 

 arteries of the Abdominal Region, and the Urino- 

 genital System of the Male. (See also Fig. 93. ) 



Open a scrotal sac along its ventral surface and note : 



(1 ) The testis, with the spermatic cord (containing the artery, the vein, and 



connective tissue), entering the anterior end. 



(2) The epididymis (mesonephros or Wolffian body), a mass of convoluted 



tubules lying along the inner border of the testis, and divided into 

 ■ a caput epididymis at the front end and a cauda epididymis at the 

 hind end. 



(3) The vas deferens (Wolffian duct), extending from the cauda epididymis 



into the abdominal cavity and there looping over the ureter where 

 that duct opens into the bladder.
