Great and informative video! Just one important point: Your concept of hemorrhoids is not right. Hemorrhoids do not develop because of high pressure in the venous collateral system. Hemorrhoids are not associated with portal hypertension. In portal hypertension you can see rectal varices which are absolutely not hemorrhoids. Hemorrhoids are specific organs of the anal canal which develop during fetal life. They are erectile tissues and better called corpus cavernosum ani. This is an essential aspect of anorectal anatomy and physiology.

Wow, this was really helpful in demystifying embryology. You made it really fun and easy to understand. Thank you Doc.
I love your new intro! It looks really good!
Thank you, very helpful.
👍
Amazing stuff❤

According to Mayoclinic, hemorrhoids are swollen veins in the lower rectum.
❤ this is amazing.
Thank you 😊💚
Thanks!!
Very helpful💘💘💘💘💘
It's a waste. You should elaborate more on embryo. U r telling more of anatomy
It is not a waste, I learnt from this
This is not a waste. This basic understanding is very important. If you need more embryology you can refer a book.
