1. Pregnancy

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

3. Zygote
The genetic material of the egg and sperm combined to form one cell

4. Implantation

5. Cleavage First Mitosis division of zygote, first 30 hours
Begins in Fallopian Tube, continues through Uterus
Trip takes 3 days, creating ~16 cells on the way.

6. Embryo
The term for a developing pregnancy from fertilization to the end of week eight

7. Spontaneous Abortion
Risk of lost embryo due to break down of corpus luteum and decrease of estrogen
Typically occurs when implantation is at the end of ovulation phase

8. 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

9. 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

10. 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.

12. 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

13. First Trimester The first 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

16. 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 inches long and about 2 pounds

18. 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

19. Fetus
A developing human, from the start of the ninth week of pregnancy until delivery

20. Fetal Blood and Circulation
During fetal period, live and aorta are connected to Placenta via Umbilical Arteries for oxygenation and waste removal

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. Birth Process 1. Rupture of Amniotic Sac (Water breaks)
2. Dilation of Cervix
3. Expulsion of fetus
4. Expulsion of placenta

23. Labor/Natural Birth

25. 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.

26. Vernix
Vernix is the waxy or "cheesy" white substance found coating the skin of newborn humans
Vernix is composed of sebum (the oil of the skin) and cells that have sloughed off the fetus' skin.

27. 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 when child is 2
