key developmental stages - Fertilization
Blastogenic stage
Embryonic stage
End of first trimester
Fetal Stage
Tobacco use can - increase the risk for miscarriage, stillbirth, preterm delivery, and
low birth weight infants
Alcohol use - is linked to a risk for fetal alcohol syndrome, which results in physical
and mental disabilities and growth retardation
drug use - increases the risk for low birth weight, preterm delivery, miscarriage,
birth defects, and infant addiction.

Fertilization - (Day 0): An egg and sperm unite and produce a zygote.
blastogenic stage - (Day 1 to 14): A period of rapid cell divisionDay 14: An embryo is
formed.
embryonic stage - (Week 2 to 8): The organ system develops.Week 5: The heart
begins to beat.Week 8: The embryo is now known as a fetus.
end of first trimester - Most organs are formed, and the fetus can move.
fetal stage - (Week 9 to 40): Period of continual growth and development
Beginning at conception, an egg and sperm unite and produce a - zygote
after the zygote is produced, over the next 14 days cell division occurs rapidly and is
referred to as which stage? - blastogenic stage
At its conclusion on day 14 of the blastogenic stage, an _______ is formed. - embryo
Weeks 2 through 8 are called the - embryonic stage
what is the major thing that develops during the embryonic stage? - the organ
system develops
what is the major development at week 5 of the pregnancy? - the heart is beating
By week 8 the embryo is known as a what? - fetus
Weeks 9 through the remainder of the pregnancy are called what stage? - fetal stage
are periods of growth
what is the major development by the end of the first trimester? - most organs are
formed, and the fetus can move
During the pregnancy what provides oxygen and nutrients from the mother's blood to
the fetus and also allows for the transfer of waste from the fetus and into the
mother's system for excretion? - the placenta
what is the length of a normal pregnancy? - 40 weeks and is divided into 3
trimesters.
first trimester of pregnancy - During this period: extremely important time for
development and growth
-During crucial periods of development, exposure to toxins & inadequate nutrient
