ATI Science- Reproductive System Flashcards
Functions of female repro system
produce ova, transfer ova to fallopian tubes for fert, receive sperm & provide protection for developing embryo
produce ova and secrete estrogen & progesterone
ovaries
carry mature eggs to uterus; fertilization occurs here
fallopian tubes
where fertilized egg implants; protects and nourished embryo until birth
uterus
muscular tube that receives semen from intercourse; serves as birth canal when needed
vagina
Phases of ovarian cycle
Follicular phase, ovulation, luteal phase
stimulates the production of follicles on the surface of an ovary
FSH (follicle stimulating hormone) Follicular phase
process where a mature egg is released from the ovary, and makes moves along FT to uterus
ovulation
Ovulation is induced by an increase of what hormone?
LH (lutenizing hormone)
phase when the follicle that burst and released the egg (during ovulation) develops into a small yellow cyst, called the corpus luteum
Luteal phase
phase when pituitary gland in the brain releases a hormone to stimulate the production of follicles on the surface of an ovary
follicular phase
mass of cells that form in an ovary that appears every mentrual cycle, and disappears if there is no fertilization
corpus luteum
_____ secretes progesterone and estrogen
corpus luteum
Hormones that can inhibit LH and FSH
progesterone and estrogen
hormone that prepares endometrium (lining of your uterus) for a fertilized egg to implant and grow
progesterone
shedding of uterine lining due to lack of fertilized egg implantation
menstruation
hormone that prevents corpus luteum from degrading & continues to produces progesterone and estrogen
HCG
action of giving birth
parturition
hormonal response that occurs during and after pregnancy to feed a newborn baby.
lactation
hormone that initiates milk production and ejection (releasing of milk)
prolactin
sac of skin that houses testes and keeps testes at proper temperature for sperm cell production
scrotum
male gonads, which produce sperms and testosterone
testes
stores sperm as is matures
epididymis
FSH in males does what?
stimulates sperm cell production
LH in males does what?
stimulates testosterone production
responsible for male sex characteristics
testosterone
Sperm Ejaculation Pathway
S.E.V.E.N.U.P
(testes), Epididymis, VAS DEFERNS, Ejack ducts, (none), Urethra, Penis
transports mature sperm to the urethra in preparation for ejaculation
vas deferens
secretes milky white fluid w/ proteins and enzymes as part of semen
prostate gland
How many tissue layers does the uterus have?
3 (endometrium, myometrium, perimetrium/serosa)
