Becoming Crow Lady

These last few weeks I've been wrapping up with teaching nursing students about OB.  I discovered this youtube video about conception to birth that they have enjoyed.  It is really riveting so I thought I'd post it.

 Georgia was asking how large a human egg is and I had no idea.  I looked it up and found this amazing site.  Use the bar along the bottom and scroll it to the right.  A human egg is tiny!!  I had no idea of the scale of all these things.  It's really cool.
