B. An early embryo can exisist outside the human
body but, the fridge at the fertility clinic is not pregnant.

,What is pregnancy? ✅- menstration
-ovulation
- fertilization
-implantation
How long is pregnancy? ✅40 weeks
How many weeks is a baby considered pre-mature ✅anything before 37 weeks
-gravida ✅pregnant
primigravida ✅first pregnancy
multigravida ✅many pregnancies
Para ✅woman who has given birth
nullipara ✅a woman who has never borne a viable child
primipara ✅first birth
Mulitipara ✅second, third, etc birth (includes twins)
Quickening ✅the first movement of the fetus in the uterus that can be felt by the
mother
Progesterone ✅- thickens the endometrium (vascular)
- supresses development of a new follicle
- inhibits uterine contractions
Placenta ✅- begins metabolic exchange between mom and baby at week 4-5
gestation
- by week 14, the plancenta is a discreet organ
1st trimester ✅LMP - 14 weeks
5-6 weeks: heart begins to beat
10 weeks: major organs grossly developed and the embryo is now considered a fetus
2nd trimester ✅14-28 weeks
- detailed development of organs and fetal growth continues
- hearing develops at 26 weeks
- eyes reopen at 26 weeks
, 3rd trimester ✅28-40 weeks
- fetal growth and development continues
- fat stores improve survival
cardiac maternal changes ✅- blood volume increases 40-45%
- HR increases
- BP decreases
- Heart displaced, murmur
respiratory maternal changes ✅- increased oxygen consumption by 15-20%
- nasal stuffiness
- nosebleeds
- decreased lung volume as fetal size increases
GI maternal changes ✅- increased saliva
- nausea
- increased metabolism
- bloating, gas, consumption
- acid reflux
musculoskeletal maternal changes ✅- loose, more relaxed (progesterone)
- Backache (fetal position, wt gain)
- center of gravity changes
- Rectus abdominus separation
skin maternal changes ✅- Linea Nigra: dark line down from umbilicus
- Chloasma: mask of pregnancy
- Straie: stretch marks
- spider veins, varicose veins
- Increased hair growth, sweat
"pregnancy glow": smoother, more supple.
vaginal maternal changes ✅- pH = 3.5 to 6.0 (pre-preg pH: 3.8 to 4.2)
- altered flora
- gradual softening, stretching
uterine maternal changes ✅- 2 oz to 2.5 lbs
- capacity 10ml to 5000 ml.
- Braxton-Hicks contractions : mild, irregular
cervical maternal changes ✅soft (Goodell's sign)
vascular (Chadwick's sign)
mucous plug
