Document Summary
Male reproductive tract: use correct anatomical terminology to describe the main. Structures of the male reproductive tract: relate structure to function overview of the male reproductive tract. Testes lead to epididymis to ductus deferens (vas deferens)> internalized> accessory organs> at prostate gland we have vas deferens> urethra> enters penis> seminal fluid can then reach external environment. Seminiferous tubules= where sperm are produced, within each teste we have 300 lobules, each lobe of the testes has 1 seminiferous tubule. Rete testis= where sperm contents is emptied. Epididymis= sperm then emptied here: testis function. Androgen secretion- interstitial tissue (the interstitial cells are hormone producing) Sertoli cells support developing sperm, give nutrient/remove waste and protect them by acting as a barrier to ensure they are(cid:374)"t re(cid:272)og(cid:374)ized as foreig(cid:374) (diffi(cid:272)ult to see, elongated) 2-6 day passage sperm maturation (gain motility, metabolic changes, cell membrane changes), storage, transport, now need to get nutrients form seminal fluid, being motile requires lots of energy,
