spermatogenesis
where are spermatogenic cells stored
seminiferous tubules
where does spermatogenesis occur
seminiferous tubules
seminiferous tubules merge into
straight tubules
straight tubules lead to…
rete testes
once in rete testes… sperm will travel…
up ducts until it reaches epididymus
where sperm are stored and mature until they are expelled during ejaculation
epididymus
epididymus is where …
sperm are stored
what is the process during ejaculation…
vas deferens into ejaculatory duct
enter into urethra
and exits through penis
describe the pathway of sperm before ejaculation
testes are segmented into lobules
lobules house tightly coiled seminiferous tubules
seminiferous tubules contain spermatogenic cells where spermatogenesis occurs and sperm are produced
seminiferous tubules merge into straight tubules
straight tubules lead to rete testes
sperm will travel up duct until it reaches epididymus where sperm are stored and mature until ejaculation

prostate
what accessory organ contracts during ejaculation pushing secretions into urethra
prostate
what does the prostate do during ejaculation
contract move semen into urethra and mix it with sperm to activate it
what accessory gland discharge components of semen into urethra
bulbourethral gland
accessory gland that produces mucus that lubricates glans penis
bulbourethral gland
accessory organ that is located near the prostate
bulbourethral gland
what kind of cells are gametes
