othe’s loodstea; allos aste to pass out
Embryonic stage:
o 2-8 weeks
o buds for limbs form and grow
o major organs/ digestive system differentiating
o heartbeat begins
fetal stage:
8 weeks- birth
buds for teeth form
sex organs develop rapidly
arms/fingers move
o 4th month:
face looks human
lower body outgrows head
bones are defined
o 5th month:
fingernails and toenails appear

gooey stuff that helps baby slide out and looks gross when born
o 6th month:
eyebrows/lashes well defined
eyes completely formed
o 7th month:
fetus capable of life outside the uterus
age threshold of viability has now changed and considered to be 23-26 weeks instead of
27-28
