the structure and function of reproductive organs and gametes Flashcards
gametes are produced
germline cells by meiosis
sperm are produced in
seminiferous tubules in testes
interstitial cells produce hormone
testosterone
ovaries contain
immature ova(eggs cells)
ovum is surrounded by a follicle that protects
the maturing ovum and secretes hormones
mature ova are released
into the oviduct where they may be fertilised by sperm to form a zygote
a zygote undergoes mitosis to produce a
blastocyst, which implants into the endometrium then develops into an embryo
Blastocyst
cellular structure that implants and becomes the embryo and placenta
corpus luteum
formed from a follicle after ovulation; produces progesterone
endometrium
inner lining of the uterus
follicle
cluster of cells in the ovary that matures to release an ovum
gamete
sex cells containing the haploid chromosomes number
interstitial cells
cells in testes found between the seminiferous tubules; produce ICSH
seminal vesicles
glands producing fluid that forms part of the semen
seminiferous tubules
very narrow tubes in the testes in which sperm cells are produced
