ORGANSORGANS THE UTERUS- An organ
also known as the
“womb.” It is a pear
shaped organ that houses
a developing fetus. There
are 2 parts: The lower
part which is the cervix
and the main section
which is called the corpus.
THE CERVIX- The
narrow end of the
uterus that is closest
to the vagina.
THE VAGINA-
Known as the “birth
canal,” this joins the
cervix to the outside
of the body.
THE OVARIES- Oval
shaped glands that
produce eggs and
hormones
FALLOPIAN TUBES-
Attached at the upper part of
the uterus, these tubes function
as a traveling tunnel for
mature egg cells to go from the
ovaries to the uterus.

and development will continue.
Around the middle, fetal
movement can be felt. Due to the
stages of development by week 16
ultrasounds are usually
performed because the baby’s sex
can now be determined.
The last trimester is considered
the home stretch. Most of the
weight gain occurs during this
last phase.
Toward the end of this trimester
the baby’s head descends into the
pelvic cavity in preparation for
labor and delivery.

10. LABOR AND DELIVERYLABOR AND DELIVERY
 There are 3 stages ofThere are 3 stages of
labor.-labor.-
The first stage is known as
early labor. It is the longest
stage, lasting anywhere from
hours to days long. The
contractions are 5 to 20
minutes apart and last until
the cervix is dilated to 3
centimeters. The cervix should
be 100% effaced and the
woman should be at the
birthing center of her choice.

11. Stage 2 is known as active labor. It can last from 1 to 5 hours.
During this phase cervix dilation occurs faster. The mother will
dilate from 4 to 7 centimeters. Contractions come every 2 to 5
minutes and last from 45 to 60 seconds long. It is the most intense
stage of labor.
The third stage is known as the “transition” stage. Contractions
are every 2 to 3 minutes, and last from 60 to 90 seconds long. This
phase last about 30 to 90 minutes. The cervix goes from 7 to 10
centimeters dilated.
After stage 3 the woman will begin to push with each contraction
she has. In a normal delivery there is no time frame on how long
she will push. The baby’s head is usually the hardest part to push
out. Once this is done the rest of the body will be delivered. Once
the umbilical cord is cut, the delivery of the baby is complete. A
few minutes later the mother will deliver the placenta.
