15 Amazing Facts About The Placenta, Umbilical Cord and The Amniotic Sac

I find pregnancy so fascinating! Not just the crazy idea of this little thing growing into an actual human, but all the things that need to take place in between sex with a partner to birthing a baby. We often talk about the changes that happen to the mom when pregnant, the pregnancy symptoms, the weight gain the “oh crap I can’t see my feet any more” moments, but there really are some behind the scene things that are equally as interesting.

I will admit, I had never seen a placenta in real life or photo-form until after the birth of my first child and I accidently saw it sitting in a bucket in front of me. I was both totally disgusted and intrigued at the first time. I had no idea it would be so big and look like an organ. It is an organ, but I guess I never really thought too much about it. Since then, I have been really fascinated with learning more about the things I didn’t really think about. Week-by-week I was reading up on what the baby was doing — what new changes he underwent, but paid little attention to the three vital aspects of pregnancy — the amniotic sac and fluid, the placenta and the umbilical cord — there would be no babies with out them.
