5. Each of us begins when two cells, one from the mother and one from the father, join. These cells are too small to be seen without a microscope, yet their union is the beginning of every human life.

6. Conception and Pregnancy
Fertilization – also called conception, is the union of an egg from the mother and a sperm from the father.
Zygote – the united egg and sperm. Within 36 hours, the zygote begins to divide into two cells, then into four, and so on.
Blastocyst – The zygote grows into a hollow sphere. Once this happens, it begins to attach itself to the wall of the uterus.

9. Implantation – Within four to five days after fertilization, the blastocyst reaches the uterus and implants itself.
Pregnancy Testing – During the implantation process, progesterone levels remain high which causes menstruation to stop. Pregnancy can be determined once implantation occurs due to HCG (Human Chorionic Gonadotropin).

11. The Embryo
Placenta – the attachment that holds the embryo to the wall of the uterus. After about 25 days a cord develops between the embryo and the placenta. The cord is called the umbilical cord. The umbilical cord is the embryo’s lifeline.
The developing embryo is enclosed in a bag of thin tissue called amniotic sac. The sac is filled with amniotic fluid.
At the end of the second month of pregnancy, the embryo is called a fetus.

13. The Fetus
