Organs And Gametes Flashcards
Gremlins cells divide by meiosis to produce what?
GAMETES
Where are sperm produced ?
Seminiferous tubules in testes
What do interstitial cells produce?
TESTOSTERONE
What do diploid gremline cells divide by and to form what ?
Divide by mitosis to form more diploid gremline cells
OR
by meiosis to produce haploid gametes
What do the prostrate glands and seminal vesicles do?
Secrets fluids that maintain the motility and viability of the sperm
What are seminiferous tubules lined with?
Gremlins cells
Where are interstitial cells found ?
Between seminiferous tubules in testes
What does testosterone do?
Stimulates sperm production
Prostate -secretion and role?
Secrete enzymes
Role - keep fluid at correct consistency for efficient swimming of sperm cells
Seminal vesicles - secretion and role (2)
Secrete fructose
Role - despised to provide energy for sperm to swim
Secrete prostaglandins
Role - cause muscles in female reproductive system in contract, helping move sleek cells towards oviduct
What do the ovaries contain and what do they do?
Contain Immature ova (egg cell) and gremlins cells
AND
release the ova and the hormones oestrogen and progesterone
Where are mature ova released to and what happens there?
Oviduct where they may be fertilised by sperm to form zygote
What process does a zygote go through and to form what?
Undergoes mitosis to produce a blastocyst
What does a blastocyst do?
Implants in the endometrium and develops into embryo
What is a corpus luteum
Formed by a follicle after ovulation to secrete progesterone
