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.
