Ovulation occurs when one mature egg leaves a woman's ovaries and makes it's way to her fallopian tube. 

Next, fertilization begins when a man's sperm attaches itself to the woman's mature egg, in the fallopian tube.  When the sperm meets the egg, the sperm penetrates the egg.  During this time, the genetic makeup of the baby is created and the sex is determined.  The fertilized egg now becomes a zygote.      

The zygote contains 46 chromosomes, 23 from the female and 23 from the male. 22 of the chromosomes are identical and the 23rd is not, this is the sex chromosome - it determines if the baby will be a boy or a girl. A female zygote has XX chromosomes and a male zygote has XY chromosomes. 

Lastly, the zygote will make its way to the uterus during implantation. This journey normally takes up to two weeks.  Once the zygote attaches itself to the uterus, it then becomes the embryo.]]> 2016-10-03 19:44:05 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/128001863 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/128002279 Once the embryo attaches itself to the uterus, it's major organs begin to develop.  This period within prenatal development is called the Embryonic Stage and it last from the 3rd - 8th week of pregnancy.  During this stage, major organs are formed. These organs include the heart, brain and central nervous system. ]]> 2016-10-03 19:45:58 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/128002279 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/128003195 A pregnancy consist of three trimesters.  The first trimester last from the 1st - 13th week, the second is from the 13th - 27th week and the third and final is from the 27th week until birth. During this 9 month period, both the mother and her baby will grow! 

At 40 weeks a baby should be fully developed and ready to enter the world!

This period last until the baby is born. During this time, the fetus experiences a great deal of prenatal developmental changes. These changes include: fingers, toes, lungs, muscles and bones develop, hearing begins, sex organs are created, etc.]]> 2016-10-07 14:52:40 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129145165 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129162397 During the entire pregnancy it is extremely important for expecting mothers to live healthy lives.  By eating healthy, exercising, reducing stress and not consuming alcohol and drugs, a mother is bettering the chances of her baby living a healthy life.

Vaginal Labor occurs in three stages:
Stage 1: Begins when the cervix begins to dilate until it is fully dilated at 10cm.  During this time, mothers will begin to experience contractions.  Contractions are normally most painful when the cervix is expanding from 4-8cm wide.

Stage 2: Begins when the cervix is fully dilated until the baby is born.  During this stage, mothers begin to push.  The stage concludes once the baby has exited the mother's vagina.

Stage 3: This is the last stage, it begins once the baby is born and ends when the placenta is separated from the uterus and exits the mother's vagina. ]]> 2016-10-07 15:57:03 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129170447 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129176876 The beautiful baby can explore the world and continue to develop and mature! ]]> 2016-10-07 16:18:02 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129176876 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129178192 2016-10-07 16:21:18 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129178192 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129179189 2016-10-07 16:23:40 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129179189 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129246983 A woman can either give birth by having a cesarean section (c-section) or a vaginal labor. 

A c-section is the delivery of a baby through a surgical incision in the mother's abdomen and uterus. Sometimes a physician requires that a mother has a C-section, rather than a vaginal labor, due to a health issue or threat. Other times, C-sections occur if there is a complication during a vaginal labor. ]]> 2016-10-07 20:38:07 UTC https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129246983 kmb5736 https://padlet.com/kmb5736/x3zt38s1vnuv/wish/129247382
