Lockdown Embryology with Prof Alice Roberts #14: Urinary System

Tiny tubules start to form within intermediate mesoderm; the definitive kidney develops from the metanephros and its collecting system from the ureteric bud which sprouts from the mesonephric duct. The bladder develops from the urogenital sinus - the anterior portion of the cloaca at the end of the embryo’s hindgut. The urinary and genital systems are closely related in adult anatomy - and very closely related in embryonic development:

finally a simple well explained video thanksssssssssssss😭😭😭

[@rayanballuz]

This is magnificent, 2 days till my end of hear medical school exams and I finally appreciate urinary embryology. Thank you for the beautiful drawings, and succinct, clear and perfect explanations. If only i found this channel earlier XD

[@johnbarnes6568]

Professor and embryology in perfect harmony.

Hi Alice.The simplicity of your videos and the way you explain things is greatly appreciated... Have a great christmas! lol

[@aliceroberts4107]

Oh thank you!

[@Maydai-gx3gq]

Thanks Prof Alice Roberts, beautiful drawings and clear illustration. but I'm a bit confused why mesonephros and metanephros are colored in blue not orange, the color representing mesoderm which they are originated from...

[@michaelkyriacou7026]

Fantastic,the creator really knew hes stuff... ;)

YO LA QUIERO MUCHO BELLA DOCTORA ALICE

[@amber8848]

Very nice drawing mam and also teaching method 👍

[@gazpitt8087]

👋😊

[@davidroach8277]

Does the pronefros (please excuse my spelling if wrong) that come in and out of existence in human embryology still exist in other mammals after the embryonic stage...i.e whales.

[@aliceroberts4107]

No - it disappears in most vertebrates and only persists in few groups of fish, who possess a head kidney.

[@Yanquetino]

I had NO idea that we lose the pronephros, yet other organisms retain it. Having experienced the worst agony imaginable several time, it makes me wonder if such organisms could develop "kidney" stones as an excrutiating pain-in-the-neck. And I must say: if there were a "designer" of our bodies, how idiotic to make the ureter such a ridiculously small tube, with over-the-top pain nerves. Sheesh! Of course, that major design flaw doesn't usually manifest until after we've propagated and passed the genes along, perpetuating the problem.
