Flashcards in Female Reproductive System Deck (21)
1

female reproductive system

composed of the ovaries, uterine tubes, uterus, vagina, external organs (vulva and mammary glands)

2

location

lies witihin shallow deepressions, superior to the pelvic region and lateral to the fundus of the uterus

3

ovaries

produce ovum, secrete horomones

4

oogenesis

formation and developement of ovum
one ovum matures each month and is available for fertilization by the sperm

5

ovum (ova)

mature female reproductive cell

6

estrogen

responsible for development and maintenance of female accessory sex organs
responsible for secondary female sex characteristics

7

progesterone

responsible for preparing the endometrial lining for implantation of the fertilized ovum

8

uterine (fallopian) tubes

two tube like structures that connect to the fundus of the uterus and extend laterally toward the ovaries
transports fertilized or unfertilized ova to the uterus
distal 1/3 of the uterne tubes are usually the site of fertilization

9

fertilization

can occur at any time within 12 to 24 hours of ovulation

10

ovulation

the discharge of a mature unimpregnated ovum from te ovary

11

fimbriae

fingerlike projections located at the most lateral portion of both uterine tubes
after ovulation, by movement, the fmbriae create currents that sweep the ovum into the uterine tube

12

uterus

pear shaped, hollow, muscular organ
serves as part of the pathway from sperm to reach the uterine tubes
site of menistration, implantation of the fertilized ovum, and storage are for the developing fetus until delivery

13

perimetrium

the outer layer that surrounds the uterus and covers the myometrium

14

myometrium

the inner layer of muscle that contracts during deliver to expel the fetus from the uterus

15

endometrium

the innermost layer of tissue that serves as the site of implantation of the fretilized ovim and is also the layer that sheds during menstrual flow

16

fundus

superior portion of the uterus
level at which the uterine tubes attach to the uterus laterally

17

body

middle portion of the uterus

18

cervix

inferior portion of the uterus
serves as the opening to the uterus from the vaginal canal

19

vagina

muscular tube that makes a 45 degree angle with the small of the back and ends at the cervix of the uterus

20

vagina functions

passageware for menstrual flow to exit the body
passageway for the fetus during delivery
female organ for sexual intercorse

21

mammary glands

develop when exposed to periodic stimulation from estrogen and progesterone during puberty
produce mil for nourishment of the newborn baby (lactation)
