Being a Chem: Pre-Med major I have had a lot of the biological development stuff, but being able to see it from a psychology stand point is really amazing. It has allowed me to see a baby not as just a fertilized egg, but an actual human. These first few chapters have also allowed me to understand how I have become who I am today. I want to begin by touching on how absolutely fascinated I was learning the specifics about the development of a baby, first from a zygote then to a fetus then to an embryo. As I mentioned in our discussion, I had no idea that fertilization actually occurs in the fallopian tubes. I thought that that only happened by accident and the result was an ectopic pregnancy. Although that was an embarrassing fact to learn, I now understand better why it is so hard for the sperm to find the egg, as the fallopian tubes are much further than the uterus, which is where I thought that fertilization actually happened.
