what are the functions of the oviduct

Answer 9

move sperm and oocyte toward each ohter
supports early embryo development
transports embryo to uterus

what are the portions of the oviducts

Answer 10

infundibulum
ampulla
isthmus
uterotubal junction

Question 11

describe the infundibulum

Answer 11

catches the oocyte and guides it to oviduct
blood causes swelling to contact the ovary (estrogen)
sends oocyte to ostium

Question 12

describe the ampulla

Answer 12

high SA and cilia
propells oocyte
location of fertilization

Question 13

describe the isthmus

Answer 13

transports sperm to oocyte
transports fertilized ovum

Question 14

describe the uterotubal junction

Answer 14

regulates movement of embryo to uterus
restricts sperm movement to oviduct
prevents movement of unfertilized oocytes

Question 15

describe oviduct mucosa

Answer 15

ciliated for motility and nonciliated for secretion

Answer 16

dictate whats going on

Question 17

when is there more cilia? when is there less cilia

Answer 17

more cilia before ovulation
less after ovulation

Question 18

define ampulla

Answer 18

contains more mucosa and submucosa; more cilia and secretion

Question 19

define isthmus

Answer 19

contains more muscle for increased contractions

Question 20

what are the uterine functions

Answer 20

transport sperm
expel fetus and placenta
absorption and phagocytosis
partially prepares sperm for fertilization
provides environment for embryo and fetal growth
produces prostaglandin F2a

Question 21

what does prostaglandin f2a do

Answer 21

causes corpus luteum to go away and decrease progesterone secretion
increases at end of pregnancy to increase contraction strength
