Unreal video , spent 3 days looking at my medical school lecture slides, didn't understand shit(pardon the pun), with one 30 minute video you acc cleared it all up . Legend

and at the end of all that Gold, he’s the one thanking me ‼️🤯

Just finished watching the small intestine motility video, 18 seconds later, large intestine motility is released !! Hells Yeah :D

This sir deserves himself a medal! I have final exam for physiology in 1 week, and I wasn´t understanding s***t about all this motility process. with you I finally got it! Thank you so much! Btw, I saw the video of gastric secretion, but could you do a video about Intestinal + Liver secretion? xD cheers

Man, your illustration of the Valsavas maneuver is priceless, thanks for the great content!

I'm a biology teacher just brushing up on university stuff for a premed exam and this was gold. So rare to find a well articulated, funny and knowledgeable video/presenter! Smashed it dude.

THANK YOU!!! You're honestly getting me through medschool, I would know literally nothing without you.

Most memorable physiology lecture I've seen thus far! (couldn't help but to smirk when you were talking about evacuation of the poop). I will never forget large intestine motility :D

Dang, just got out of GI block, thanks for carrying me through medical school by the way. I am trying to get my medical school to give you half of my tuition but they seem against it

Very well done! I’m not in medical school but I’m trying to learn about gut health and common ailments/ symptoms. If I can follow this, without a day in med school, then your med students should definitely be able to follow along. The beauty about this video is you included the out lying functions to describe how much the rest of the body is involved in gut health. Thank you!👏🏻👏🏻👏🏻 job well done!

We should be the one thanking you! This channel is my Bible and a Goldmine.

It's 3:30am and u made me laugh desperately with the poop thingy hahaha u are great

I have motility issues and found this very helpful in seeing how everything works.

I love you Bro! I am preparing for my USMLE exams soon. Please do all the basic medical subjects in details like this. Thank you very much for all the hard work !

You're literally making life easier for so many of us. Thank you ❣️

I am not a medical student. I watched this video a few times to understand my gut problems. Thanks for a very educational video.

We love you too !!!! :D Today I've just gone through the GIT in pathological physiology and what I've found on YT? Brand new videos about intestines!

I almost finished your all playlist except a few ones. So thanks to you, ninja nerd science! Lectures so far are so helpful for studying. I hope I could donate to your channel by getting scholarship in this semester. Studying in medical school used to be always boring and exhausting, but now it doesn't!! thanks to your channel.

I LITERALLY LOVE THIS MAN AND ESPECIALLY HIS PASSION ! thank youu soooooooooo muuuuuuch sir !!

Good Lord, this man is an amazing professor! His videos are super well explained and his drawings make it all so much easy to understand. I LOVE your videos! They do really help a lot. Thank you, really.

Man, this guy can make science be fun. Loved the example of Chipotle and your external sphincter holding on for dear life.

How much generous can you become dudeeee... he is thanking us after that golden lecture !!!! Thanks ain't enough for you doc 🙏

Thank you kindly for all your videos. With respect to the segmentation/haustrations, a large component comes from the circular muscle contracting , combined with the contraction if the taenia. With these contractions localized to a point, the unstimulated portions of large intestine bulge outwards into these space called haustrae

Like every one said; this was a great lecture! I needed a refresher of these concepts as a nurse and you did a great job. Hope they pay you well 😊

Thank You Ninja Nerd for amazing teaching method 👍 easy to understand.

Just in time for revising the GI block before finals. If you're still making videos when I graduate, I'll write you champs a cheque. Much love and many, MANY thanks for all that you do :)

Excellent video! I had my rectum removed due to rectal cancer and have been trying to understand how feces is processed/moved through the large colon. Thank you!!

I'm not med student,but I'm literally addicted!!!❤ Thank you !!!!

Thank you for all the great explanations ! Anyways , I was wondering if you guys can make us a video about nucleotides metabolism . It would be much appreciated ! Thank you guys again for all the hard work and God bless you all .

Great Sir, My daughter had problem of defecation reflect and for months and months she did not feel any urge. Being father and knowing the origin of the problem , I tried to convince Neuro Physicians and Surgeons and Gastroenterologists that it is related to nerve and no body believed that and today I found evidence to my proposition. At last I turned to Homeopathy and the problem was "Magnecium Carbonicum"

Can you please upload a video on viruses, its classifications, as well as its mechanism of actions. A lot of people (especially non-medical people) need awareness on this. 🙏🏻

Nothing better then learning while being able to chuckle. Great for refreshing and connecting the dots. Thank you for making me laugh and the great teaching. Never 😴 bored.

Dude, you are a Superman at linking information together

Thanks Dr Am a medical student you made my understanding easier, thanks you lots

Ok I am only a fourth of the way through this video and I am in love. You are nailing this presentation! And in the process teaching more than my gastro doctor's even seem to even know. I think I just figured out my gut problem. Whoa.

Magical. Your concepts are super clear. Thank you.

Great video, posted so many things onto my insta story because this shit was so funny. Zach and NN crew, y'all are life savers and hilarious. Yall are the best professors Ive ever had.

Thank god I found this channel, keep up the good work

Amazing lecture! Thanks for sharing all that! Small sidenote: in the large and also already in the small intestines, electrolytes prominent are sodium acetate, propionate and butyrate e.g. ... they are utilized by the intestinal wall metabolism as a primary energy source....most classic lectures are not even mentioning that

Very good your teaching capacity.

TOP quality education right here. Zack youre a star!

Thanks for explaining the Large Intestine. Their are thousands of us that have had colon cancer and had a Lower Anterior Resection and we have had little control of motility of our colons.. We can not control when our colon will discharge feces. We suffer constipation and/or diarrhea along with clustering (repeated defecation for hours). We understand that usually happens because the 'nerves' are cut during the resection and sometimes they don't heal. This is called Lower Anterior Resection Syndrome (LARS). There is even a Facebook Group dedicated to this group of people. Do you know of any studies or other research that is looking at this problem? The only 'real' 'cure' currently is a permanent colostomy.

Amazing job Zachary! I love the way you explain the content.

Really interesting, especially that I have no rectum or sigmoid. I wonder of theses nerves were cut too. Trying to get back to normal is difficult.

"restock the lake of brown trout" amazing

Are there different Valsalva Manoeuvres (VMs)? This one when 'bearing down' to defecate. A different VM to clear temporary deafness due to Eustachian Tube Dysfunction or to equalise in an aircraft or when diving? Quite different manoeuvres. Performing a VM when lifting weights can lead to a elevated intracranial pressure and brain (or was it meninges) bleed.

best teacher!!

Wow! Great lecture/lesson.

thank you so much!! you save my life in med school again T^T

Congrats on 11.5 lakhs ninja nerd❤️

Hey, what would we have to do to get you to do lab diagnosis videos on your ninja nerd medicine channel? Ps. Love the videos. I recommend you to everyone at my school

We need overview video about gi motility❤

You’re a life saver i swear💘💘💘💘💘

wow dude you are good excellent potraial ...i have big problems I cant go or have any feeling to go I have to use a laxative i dot know how to fix this

very nice work. clear and easy explanation. im bout to get a colonoscopy. my doc doesnt understand thec absorbtion value of the large colon. you stated that within a few minutes. b vitamins and electrolytes. my understanding is that each pocket feeds seperate systems as well. maybe there is something to it, as you attributed seperate nerves being affected. ...i bet you study basic chiropractic as well.

Amazing explanation

Golden video

Thanks Prof God bless you

What’s the muscle that causes you to feel like you’re always in go mode? Or always stimulated ?
