Who'da thunk it?

Let me expound on why I think embryology is so amazing. Embryology is the study of development...in this case, human development. I'm not sure how many people realize that all of our organs don't just come to being as they are found when we are adults. Cells form organs, connect in places, twist, turn, move up and down, and miraculously, a good majority of babies are born "normal."
***WARNING - NERDY MEDICAL TERMS TO FOLLOW - WORTH IT IN THE END***
I was studying tonight and just wanted to share with everyone (all 3 of you that read this) a crazy possibility. A babies developing kidney is known as the mesonephric duct, which originally drains into the cloaca. The cloaca, which is like a wasteland, will divide into the urogenital part and rectal part, so now we have urine and poop covered. The urogenital part is continuous with the allantois which, as many will know, is where the umbilical cord is (belly button after birth). Eventually the allantois will constrict, called the urachus, and form a ligament that connects the bladder and the belly button. Here's the big finale...there is a rare condition known as a urachal fistula where the urachus remains patent or open (never constricted), which will allow urine to escape through the belly button! You can leak urine through your belly button...ha!
Isn't is amazing how many babies are born without these conditions?

Our bodies are so amazing! I have no idea how people can really believe that we just "happened" to all come together like this. . .especially people who study medicine?! How can they believe that the way we are designed was NOT a plan?

hey maybe when I start school next week I can bore you with Greek stuff, although this wasn't too boring, I mean it was boring until you got to the "punch line" I think it would be pretty cool to pee out your belly button, or not. ok bye.

Would that condition fix itself? B/c Garrett was born with something not all the way closed up right by his belly button that fixed itself - was that it, or was it just a hyrnia?

probably something different...i don't think resolves itself. would probably have to be surgically fixed. I don't know what he had.
