ACTUAL QUESTIONS AND CORRECT
ANSWERS
in the 20th century, what significant changes happened in childbirth? - CORRECT
ANSWER Birthing was moving away from the home and a midwifery model of care,
into a hospital medical model of care
*d/t high infant/maternal mortality rates
T/F Most pregnancies are not confirmed until after organogenesis has commenced -
CORRECT ANSWER true
what is conception? - CORRECT ANSWER when egg and sperm meet and they fuse
together
cells are produces by what 2 methods? - CORRECT ANSWER 1) mitosis
2) meiosis
what is mitosis? - CORRECT ANSWER a type of cell division that results in two
daughter cells each having the same number and kind of chromosomes as the parent nucleus
what is meiosis? - CORRECT ANSWER a type of cell division that results in four
daughter cells each with half the number of chromosomes of the parent cell, as in the
production of gametes
when does the placenta form? - CORRECT ANSWER at implantation
when is the maternal-placental-embryonic circulation i place? - CORRECT
ANSWER by day 17 when the hear starts beating
, maternal component of placenta formed from? - CORRECT ANSWER decidua basalis

3) Progesterone

ensuring a continued supply of estrogen and progesterone needed to maintain pregnancy
fx of hPL? - CORRECT ANSWER stimulates the maternal metabolism to supply
nutrients for fetal growth

membrane
stimulates breast development in preparation for lactation
