Good times with bladders.

Here we present a couple of animation videos that show the organogenesis of the urogenital system. All of these developments happened months back, but around this time Baby Chaud's prostate/uterus should be about ready to click on and complete some of the final developments of the kidneys, bladder and sex organs.

The entire system is a pretty bizarre one as far as human development goes - we actually grow three sets of kidneys in increasing amounts of evolutionary advancement. These are the pronephros, the mesonephros and the metanephros, the latter of which develops into our functioning kidney. Boys and girls have the real distinction here, using Wolffian and Mullerian ducts respectively to create their unique plumbing parts. It's also of note that these two systems are really involved, each contain and influence each other's growth until they become the systems useful to the body.

The videos have French subtitles, but just enjoy the pictures, they say more than enough.



C'est bien, comme ca!
