Epididymis
Long tube; transports sperm
Ductus (Vas) Deferens
conduit to urethra, thru prostate
Ejaculatory Duct
Ampulla of Vas deferens + Seminal vesicle equals what?
Ejaculatory Duct
common tube for urine and ejaculatory contents
Prostatic Urethra
common conduit thru urogenital diaphragm
Membranous Urethra
from urogenital diaphragm thru penis to external urethra orifice
Spongy Urethra
produce 60% of seminal fluid; produces an
alkaline solution with nutrients for sperm
Seminal vesicles
secretion of slightly alkaline, milky fluid;
neutralizes acidity
Prostate
flush out urine before ejaculation, also slightly
alkaline; Lubricant- does not contribute to semen
