FIGURE 6 



In this sectional diagram of the sex organs of the human male four principal structures 

 will be noted: The bladder I, the penis II, the testis III, and the spermatic duct IV, 

 connecting the testis with the penis. 



The sperm cells of the male are produced in about 800 minute coiled tubules each of whit k 

 is fully two feet in length. After being produced, the sperm cells are collected in larger 

 tubes and are passed on to the long {20-foot) epididymis V, the much coiled beginning of 

 the sperm duct. This structure lies clcse about the testis, but is separated here in order 

 to show its relation to the testis. The epididymis is continued in the vas deferens or sper- 

 matic duct proper, IV. The spermatic duct passes in front of the pelvic bone, around the 

 side of and below the bladder where it empties into the urethra or canal from the bladder. 

 The seminal vesicle, VI. A short duct, VII, leads from the vesicle to the urethra or canal 

 from the bladder. Glands, VIII, surround the urethra and duct. 



The diagram is made through the right testis. The testis, duct and seminal vesicle are 

 double or paired.
