Male repro
Scrotum
=specialised skin>warms & cools testes
epididymis
=where sperm matures
2 testes
=production of sperms
2 Bulbourethral glands
=produce semen
Prostate
=produce semen
Semen vesicle/gland
=semen production
Urethra
=passage of urine & sperm
Ductus deferens
=transport of sperm from epididymis to ext. environment via passage of urethra
Urethra 3 parts
Membranous urethra
-susceptible to injury>damaged with catherization
Prostatic urethra
=runs through prostate gland>>lies within gland(thus protected)
Penile/spongy urethra
-longest part>encapsulated by erectile tissue of penis
Pelvic viscera
Internal
(involuntary) &
external
(Voluntary) anal sphincters
Urinary bladder, ureters, urethra, sphincters'(2), prostate gland, seminal vesicles, bulbourethral, rectum+anus, anal sphincters'
