secrets LH and FSH
pituitary gland
secrets estrogen and progesterone
Ovary
Menstruation
days 1-4
high level of FSH causes follicle to develop
uterine lining thins out
follicular phase
Days 5-13
follicle stops developing
higher rate of estrogen thickens uterine wall
Ovulation
Day 14
egg is released from follicle
LH spikes
Luteal phase
Day 15-18
follicle in ovary breaks down
uterine lining maintains thickness due to progesterone
hormones all decrease triggering menstruation
Ovaries
site of meiosis and egg production
oviduct
where sperm fertilizes the egg
uterus
where embryos implant and develops. nourishes fetus
cervix
connects uterus with vagina and allows sperm into uterus
vagina
passage out of body
testes
meiosis and sperm production
Scrotum
keeps testes 1-3 degrees cooler than body temp so sperm can grow
epididymis
storage and maturation area for sperm
vas deferens
tube that transports sperm from epididymis to urethra
prostate/cowpers gland/seminal vesicle
produce nutrient rich liquid from sperm
urethra
transports sperm and ur one out of body
penis
organ that delivers sperm into a female body
cells begin to differentiate when
the gastrula forms 3 germ cell layers (ectoderm, mesoderm, and endoderm)
meisois reduces
the chromosome number
fertilization restores
the diploid number
placenta
exchanges materials between mother and baby
amnionic sac
fluid filled sac that protects fetus from shock
nutrients and oxygen diffuse
from mom to baby
co2 and urea diffuse
from baby to mom
