100 thoughts on “The Digestive System

  1. I scored a 50% on the pizza review. I was able to recalI the carbohydrates and the proteins because you covered them very well, but don't think the lipids and nucleic acids were covered in enough detail before the pizza review. However, this small issue was also helpful in that I am now able to recall that there are four macromolecules and what they are. 

  2. I just quoted you in my exam…. i told my class mates if i pass il marry you. <3 one true love haha 

  3. you are very smart !!!!!!!!!!!!!!!!!!!!!!!!1 you should be a permanent teacher at a health collage if thats what you want to do!!!!!

  4. Hey i think the chief cell in the stomach also secretes some lipase as well as pepsin – just sometimes they ask that 🙂 Awesome vid btw .

  5. How do the digested building blocks end up in the liver? is it via the blood? how does it reach there once absorbed by the small intestine? 

  6. I don't know how you do it Mr. Anderson, but I understand all of these biological processes when you describe them. I have watched your videos through General Biology, Biological Psychology, and A&P. Thank you for your videos, they are always the go-to explanation for me. 

  7. Why does he say the appendix is vestigal? Does'nt it help with your immune system? http://news.nationalgeographic.com/news/2009/07/090730-spleen-vestigial-organs_2.html

  8. Appendix is absolutely important. It's a storehouse for all the good bacteria the gut may need in case of a virus or invasion of bad bacteria…. which is highly common in our society… IBS etc. It is like an injection of good bugs for the gut… Most peeps don't get enough good bacteria from their food and chuck a whole bunch of bad food in… ie donuts Mr Anderson 😉

  9. Hi Paul,
     Thanks so much for your videos. I'd use it those as a real help for my Anatomy class. I love the way that you explain it. Using common simple language from everyday use to explain very complex and hard to understand concepts. its been a real asset for me. Do you have a video on how osteocytes, osteoblasts forms new bone and the enzymes that works on it? Thanks so much !!!

  10. I hit like before watching because I know mr Andersen is the best on the field here on youtube. I own a lot you mr Andersen. God bless you and your brain : )

  11. I like your movies on A&P topics: short and succinct – thank you! I noticed that you pronounce 'duodenum' differently which is a bit confusing for me (non-native speaker…) I learnt to pronounce it like this: http://dictionary.cambridge.org/dictionary/english/duodenum
    Is your way the US way to pronounce it???

  12. Hey Paul, I would love to meet you. I teach at Western in Dillon and use your videos in class ALOT! I found a share slide presentation from the UK and guess what, the second slide had a link to this video. Teachers around the whole world thank you for your work and unique and awesome way you teach. Thank you for sharing your talents and info!!!! Jan

  13. Hey Paul, I just ran across this video and was wondering what type of software you use to draw over the images? Im assuming it is on a mac, but I have wanted to do something like that for a long time.

  14. Omg who are you?? You basically just made me understand the whole digestive system completely and it was done in a simple, amazing manner. Wish I had you as a teacher, if I get a good grade it's because of you. Wonderfully explained, keep making videos. Thank you.

  15. reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

  16. Chief cell only produce pepsinogen, not pepsin. Pepsin is converted when HCI,which parietal cell secrets, meets the inactive pepsinogen

  17. I would enjoy the video more if my teacher wouldn't literally make his exams based on the video(and i mean what he says in the video is the exam) instead of using the video just as reference
