procreate

carry on the species
main function of reproductive system
produce sperm

testes
organ that develop sperm

epidydimis
vas deferens
tiny tubes inside the testes where sperm development occurs
seminiferous tubules
sperm are matured
caps and gowns
epidydimis
tube that transports sperm back inside body
vas deferens
on the distal end of vas deferens...sperm can be stored for up to 4 months
ampulla
directly inferior ot the urinary bladder...gives antibacterial agents to secretions
prostate gland
section ro part of the vas deferens that cuts through the prostate gland that leads to the urethra
ejaculatory duct
bundled together with blood vessels and nerves. The whole thing is surrounded be cremaster muscle which comes down along the base of the testes
vas deferens
3 accessory glands that produce a substance that nurtures the sperm
seminal vesicals
prostate
bulbourethral gland (cowper's)
emty their secretions into the tube just between the ampulla and the ejaculatory duct
sminal vesicals

incomplete septa

labule
special little cells surrounding the seminiferous tubules and that make testosterone
leydig
process of making sperm...testosterone is required for this
spermatogenesis
the seminiferous tubules are made our of wquarish rather large cells called
sertoli cells
job of the sertoli cells
to nurture cells as they turn into sperm
originating cell that gets stuck to the sertoli cell
germ
type of junctions that are between each sertoli cell
tight
job of the tight junctions between each sertoli cell
create blood/testes barrier
job of the blood/testes barrier
to prevent dad's blood from coming in contact with the sperm inside the seminiferous tubule...there are different markers on teh sperm and the blood would want to kill the sperm
