CHAPTER VIII. 



THE GENEEATIVE ORGANS. 



The organs of generation in the male horse consist of two 

 oval glandular bodies called the testicles, suspended from the 

 hollow between the thighs, and contained in a pendulous 

 bag called the scrotum. The ofiSce of these glands is to 

 secrete the seminal fluid which is essential to impregnation. 

 Two membranous ducts (vasa deferentia) which carry the 

 semen from the testicles to two oval bags (vesiculce seminalis) 

 lying near the upper surface of the neck of the bladder, from 

 which during copulation it is ejected into the urethra, and 

 conveyed by the external organ, the penis, into the vagina of 

 the mare. 



The female organs of generation are : the vulva — that 

 part seen in the perineum immediately below the anus ; the 

 ijogrmo— the membranous canal leading from the vulva into 

 the uterus or womb ; the uterus or womb — that mem- 

 branous sac in which the impregnated ovum is contained 

 and supported during the development of the fcBtus ; the 

 ovaries — two glandular bodies similar in shape to the testi- 

 cles of the male, but much smaller. They are found lying 

 under 'the )loinS'ai little jsehind or in a line with the kidneys. 

 Their use ^s to Secrete the Ova or seed of the female. And 

 \\i& fallopian iuljes^ the canals which convey th& ova from 

 the ovaries to the womb.
