By the end of stage, the fertilized egg becomes a BLASTOCYST and plants itself in the wall of the uterus.
GERMINAL PERIOD

EMBRYONIC PERIOD
At the end of 4 weeks:
embryo is 1/4 inch in length
Heart, digestive system forms
and Placenta (afterbirth) begins developing at this period.
EMBRYONIC PERIOD
It is the term for organ formation during the 1st 2 months.
