Three parts of decidua:
* Decidua basalis * Decidua capsularis * Decidua vera
27
what day chorionic villi is formed?
11th or 12th day
28
It reach out from the single layer of cells into the uterine endometrium to begin formation of the placenta.
chorionic villi
29
At _____ weeks, the blastocyst is splitting into an embryo and placenta
4
30
At week ____ placenta takes over from a structure known as the corpus luteum
10-12
31
smooth chorion eventually becomes the chorionic membrane

Hydramnios
34
reduction in the amount of amniotic fluid
Oligohydramnios
35
transport oxygen and nutrients to the fetus from the placenta and to return waste products from the fetus to the placenta.

55
normal fht
120-16- bpm
56
measures the response of the fetal heart rate to fetal movement
nonstress test
57
no increase in beats per minute is noticeable on fetal movement
poor oxygen perfusion
58
fetal heart rate is analyzed in conjunction with contractions
Contraction Stress Testing
59
if no fetal heart rate decelerations are present with contractions.
Negative (normal)
60
if 50% or more of contractions cause a late deceleration
Positive (abnormal)
