unit- Reproductive Systern Histology of Testis In case of of the reproductive systeminda clude a pain of testes present in the lover abdomen covered by a membranous layer called Sercotum The Testis contain almost 900 seminiferous tubufer where the sperms are produced. The spirms mored into a part called Epididymis having a bead broad head portion & narrow tai'l porction & in between this the body pall of epididymis is present. The Head a is acts of epididymis y site for temporary вренть. The tail of the epididymis then leads to a paret called vas deferens, which enlarges into a pauta called Ampulla and finally into a prostrate gland. Two Seminal vessides located. an each side of the prostreate awhich discharge the feminal fluid through ejaculatory duct from urethra to cutside → Finally the weather is the east pared which connects the bestes to outside. A gland called Bulbourethral pland ore Cowper's pland is preesent at the beginning A of Differcent parts of Testis The human testis consist of diff parts life 20 Serotum, seminiferous fubules, Rete testis, epididym's, vas defereris, serminal vessicles, prostrate, Ejaculatory duct & lenethra.
