Cards

Term
menstrual cycle
Definition
puberty to menopause, females periodic shedding of tissue
Term
ovaries
Definition
oviducts aka fallopian tubes
Term
endometrium
Definition
tissue built up that is shed
Term
FSH (Follicle Stimulating Hormone)
Definition
pituitary gland secretes hormone (FSH)
-causes follicle that begins to produce an egg
-mature egg=follicle, starts to produce hormone ESTROGEN
Term
Estrogen
Definition
helps rebuild endometrium (made of nutrient rich tissues in case of fertile egg)
Term
LH (Luteinizing Hormone)
Definition
produced by pituitary gland.
LH serge causes follicle/egg to rupture forth; break through surface of ovary & into the fallopian tube
Term
Corpus Luteum
Definition
-tissue where the egg used to be
-corpus luteum produces tons of ESTROGEN and PROESTROGEN
Term
proestrogen
Definition
helps build back up endometrium
Term
IF SPERM DOES NOT MEET EGG
Definition
-LH begins to lower & corpus luteum degenerates
-estrogen & proestrogen levels lower
-endometrium wall degenerates
-wall comes out (menstration)
-once this happens, FSH goes up (cycle starts over)
Term
IF SPERM MEETS EGG
Definition
-occurs in follopian tube
-zygote makes way down to endometrium wall
-(IMPLANTATION) process when eggs nestles into wall
-cells around egg called HCG (human chorionic gonadotropin which prevents degineration of corpus luteum
Term
HCG (human chorionic gonadotropin)
(if sperm reaches)
Definition
forms the placenta
Term
placenta
(if sperm reaches)
Definition
-place of exchange between mother and babies blood supply
-begins to produce more HCG, estrogen, & proestrogen (prevents more follicles from being produced)
Term
HCG (human chorionic gonadotropin)
(if sperm reaches)
Definition
produced in massive quantities - lots get dumped out in blood supply and urine
-PREGNANCY TESTS LOOK FOR HCG!!
