The Very Beginning
Fertilization: The
union of a male
sperm and a female
egg.

cells that develop
between the 3rd and
8th week of
pregnancy.
Fetus: Group of
developing cells after
the 8th week.

Amniotic Sac: A thin, fluid-filled
membrane that surrounds and
protects the developing baby.
Umbilical Cord: A ropelike
structure that connects the fetus
with the mother’s placenta.
Placenta: A thick, blood-rich tissue
that lines the walls of the uterus
during pregnancy and nourishes
the embryo.
The 9 months are divided into 3
trimesters. SEE PAGE 472

Identical twins: result when a single egg has
been fertilized by one sperm and forms two
embryos. Identical twins have the same
genetic information, are the same gender, and
look almost exactly the same.
Fraternal twins: result when the ovaries release
two eggs and are fertilized by two separate
sperm. Each twin has a different genetic make
up and they may or may not be of the same
gender, and they do not look the same.

Miscarriage: The spontaneous expulsion of a fetus
that occurs before the twentieth week of
pregnancy. (baby no longer develops and female
has her period)
Stillbirth: A dead fetus expelled from the body
after the twentieth week.
Women who use tobacco or drugs during
pregnancy are more likely to experience a
miscarriage or stillbirth.
A miscarriage or stillbirth doesn’t mean the
mother did something wrong
Ectopic Pregnancy: The zygote implants itself in
the fallopian tube, ovary, or cervix.

Labor: Muscle contractions of the uterus and
causes the cervix to open.
Delivery: Baby passes through the birth canal.
Afterbirth: The placenta is still attached to the
baby by the umbilical cord. Contractions
continue until the placenta is pushed out.
