maintains constant temp for fetus, cushions the fetus from trauma, source of oral fluid and repository for waste, allows freedom of movement for development and symetric growth, acts as a barrier to infection, allows fetal lungs to develop

19
Q

Transfers oxygen and nutrients to fetus

Eventually becomes part of digestive tract

A

yolk sac

20
Q

Wharton’s jelly function

A

prevents compression of vessels, ensures nourishment of embryo or fetus

21
Q

placenta in place by

A

day 17

22
Q

corpus leuteum maintains progesterone until placenta takes over, placenta develops from chorionic villi which develop into

A

branches of blood vessels

23
Q

Umbilical cord-

3 vessels

A

Vein returns blood to embryo
Arteries carry blood from embryo to chorionic villi
Covered by connective tissue

24
Q

Placental functions depend on

A

maternal blood pressure

25
Q

Early function of placenta=endocrine gland produces the hormones to

A

maintain pregnancy

26
Q

HCG reaches max level 50-70 days and then

A

decreases

27
Q

Embryonic stage day

A

15 day- 8th week

28
Q

most critical time in development of organs and external features, vulnerable to teratogens

A

Embryonic stage day 15day- 8th week

29
Q

Fetal stage:

A

9th week to delivery

30
Q

,by the end of the 8th week all organ systems and

A

external structures are present

31
Q

stage of maturation for fetus

A

fetal stage

32
Q

capacity of the fetus to surrvive outside the uterus

A

viability

33
Q

first system to develop

A

Cardiovascular System

34
Q

Tubular heart beats

A

4-5 weeks

35
Q

cardiovascular system has special circulatory pathway which bypass lungs via

A

Ductos arteriosis and

Foreamen ovale

36
Q

Primary surfactant present for survival at

A

about 32 weeks (resp system)

37
Q

35 weeks is key to fetal

A

lung maturity

38
Q

L/S ration lecithin/sphingomyelin ratio

A

2:1 to be mature

39
Q

Two umbilical arteries

One vein which

A

carries oxygen rich blood back to fetus

40
Q

Rhythmic breathing movements
Ability to partially control temperature
Bones are fully developed but soft and flexible

A

week 32 of fetal development

41
Q

Surfactant=detection of pulmonary surfactant in amniotic fluid is used to determine (L/S ratio is used to determine)

A

FLM

42
Q

Lecithin is the most critical alveolar surfactant required for

A

postnatal lung expansion.

43
Q

Sphingomyelin is second

A

surfactant

44
Q

At approx. 35 weeks surfactant ratio should be

A

2:1

45
Q

conditions that decrease maternal blood such as HPTN, Placental dysfunction, infection and cortiocosteroid use causes what to FLM

A

accerlate FLM

46
Q

Conditions that retard FLM =

A

gestational diabetes

47
Q

Gestation is 280 after LMP or 266 after

A

conception
