Pregnancy Powerpoint Presentation

Pregnancy
Sexual Intercourse
 The reproductive process in which the
penis is inserted into the vagina and
through which a new human life may
begin
Fertilization/Conception
 The union of the egg and sperm that
takes place in the fallopian tubes
Zygote
 The genetic material of the egg and
sperm combined to form one cell
Implantation
 The attachment of the fertilized egg to
the uterus
 The egg is now known as a blastocyte,
attaches to one of the walls in the upper
1/3 of the uterus
 This happens within 3 to 5 days of
fertilization
 Once implantation has happened a
women is said to be pregnant
Implantation
Embryo
 The term for a developing pregnancy
from fertilization to the end of week eight
Endometrium
 The lining of the uterus
Placenta
 An organ that develops in the uterus during
pregnancy
 The placenta provides nourishment and
oxygen to the growing baby and removes
waste
 Some refer to it as the afterbirth because it is
excreted from the body following the birth of
the baby
 Most substances are passed from the mother
through the placenta to the baby
Amniotic Fluid
 The watery substance that surrounds the
growing fetus during its time in the womb
 The fluid helps to cushion the baby from
outside force
Amniocentesis
 A medical procedure used for
prenatal diagnosis, in which a
small amount of amniotic
fluid is extracted from the
amniotic fluid around a
developing fetus
 It is usually offered when there may be an
increased risk for genetic defects in the
pregnancy.
 Early amniocentesis can be performed as early as
13 weeks gestation
 Standard amniocentesis is usually performed
between 15 and 20 weeks gestation
Ultrasound
 used to visualize the embryo or fetus in its
mother's uterus (womb)
 The procedure is often a standard part of
prenatal care, as it yields a variety of
information regarding the health of the mother
and of the fetus, as well as regarding the
progress of the pregnancy.
Umbilical Cord
 A hollow rope-like tube that connects the
embryo to the placenta
 The placenta carries nutrients and oxygen to
the baby and takes waste away
First Trimester
 The 1st 14 weeks of pregnancy
 The most important trimester because this is
when the vital structures are forming
 The embryo develops all of its organs and
grows to about 1.5 inches
 The heart, brain, lungs, eyes, arms, and legs
have formed – not all of them are fully
functional
 The placenta and umbilical cord are also
formed during this time
Second Trimester
 Months 4-6 of pregnancy
 The organs continue to develop and
movement can be felt by month 4
 The heartbeat can be heard
 The fetus recognized voices and it grows
hair and nails
 By the end of the 2nd trimester the fetus is
about 14-15 inches long and about 2
pounds
Third Trimester
 Months 7-9 of pregnancy
 The fetus gains most of its weight during
this trimester and is able to grasp objects
as well as open and close its eyes
Fetus
 A developing human, from the start of the
ninth week of pregnancy until delivery
Labor/Natural Birth
 the culmination of a human pregnancy with
the emergence of a newborn infant/s from
the mother's uterus.
 Natural Birth which is most common is when
the baby is delivered through the vagina
 First stage: contractions/dilation
 Second stage: delivery
 Third stage: placenta/afterbirth
Labor/Natural Birth
Breech Birth
 refers to the position of the baby in the
uterus such that it will be delivered buttocks
first as opposed to the normal head first
position.
Caesarean Birth
 A caesarean section or csection, is a form of childbirth
in which a surgical incision is
made through a mother's
abdomen and uterus to
deliver one or more babies
 It is usually performed when
a vaginal delivery would put
the baby or mothers life at
risk, although in the last
decade it has been
performed upon request.
Vernix
 Vernix is the waxy or
"cheesy" white
substance found
coating the skin of
newborn humans
 Vernix is the Latin word
for "varnish." The
vernix (or "varnish"),
"varnishes" the baby.
 Vernix is composed of
sebum (the oil of the
skin) and cells that
have sloughed off the
fetus' skin.
Fontanelle
 Fontanelles are soft spots on
a baby's head which, during
birth, enable the soft bony
plates of the skull to flex,
allowing the head to pass
through the birth canal
 Fontanelles are usually
completely hardened by a
child's second birthday, and
will eventually form the
sutures of the neurocranium.
