1 Pregnancy

2 Sexual Intercourse  The reproductive process in which the penis is inserted into the vagina and through which a new human life may begin

3 Fertilization/Conception  The union of the egg and sperm that takes place in the fallopian tubes

4 Zygote  The genetic material of the egg and sperm combined to form one cell

5 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

6 Implantation

7 Embryo  The term for a developing pregnancy from fertilization to the end of week eight

8 Endometrium  The lining of the uterus

9 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

10 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

11 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

12 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.

13 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

14 First Trimester  The 1 st 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

15 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 2 nd trimester the fetus is about inches long and about 2 pounds

16 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

17

18 Fetus  A developing human, from the start of the ninth week of pregnancy until delivery

19 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

20 Labor/Natural Birth

21 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.

22 Caesarean Birth  A caesarean section or c- section, 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.

23 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.

24 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.
