SPLANCHNOLOGY. 



Both the ovum of the female and the sperm of the male are- 

 the secretions of glands, which are termed the genital glands, 

 male and female ; and in either sex the generative system may- 

 be said to consist of these glands, with certain accessory organs. 

 The act of coition brings the two secretions into contact. 



We have thus two systems of Genital organs to consider — the- 

 •male and the female.

MALE GENITAL OKGANS. 



The spermatic or seminal fluid of the male is elaborated in two 

 glands, situated in the scrotum, called the testicles, each being 

 furnished with an excretory duct, the vas deferens, which trans- 

 mits the sperm to reservoirs situated on the bladder, the vesiculce 

 seminales. Here the sperm accumulates, and is expelled by the 

 contractile walls of the vesiculee during the act of copulation.
