I saw this in my friend's notes today and it reminded me of ureter histology. Honestly, this is how i recognise a ureter under a microscope since year one, but of cos, some ureter lumen requires quite a bit of imagination for you to see the dog.
Actually most of them resemble the balloon sausage dog. Maybe you can look out for it the next time :)
On the topic of dog... how many of you rmbr this cartoon that use to play on saturday 1pm?
It was called 家有贱狗 and after this series of cartoon ended, it was replaced by 宇宙小毛球. I rmbr i was so sad when it was the last episode! Cos i found the cartoon really funny :)
I think i have a couple of this comic somewhere :)
