Experimenting With Stomach Acid | How strong Is It? 

Check out all the cool stuff! beacons.page/instituteofhumananatomy

“No pickles or onions because that would be disgusting” *”And here we have a human stomach”*

This stuff is so interesting when you’re not forced to watch. *Im glad you all agree.

That's quite a lot of information to digest.

For those who're wondering why the burger isn't really dissolving in the stomach acid which is meant to be strong. Your stomach acid is not just HCl. It's HCl coupled with activated pepsin which is responsible for proteolytic digestion. So, that whole piece of burger has proteins as well as fats and other stuff. It's not meant to dissolve completely. But also, stomach doesn't digest food or dissolve it. It just keeps it semi solid when it is passed down the deodenum! Hope it helps!

Everyone’s so thankful to the first guy who donated his stomach, but the guy who had his turned inside out is the real champ here.

I’ve never seen a man so comfortable holding an actual human stomach in his hands.

15:25 this part where he tries to show us the fizzing is so adorable. Also the curiosity that he had to have to drop acid on the latex glove. I hope we have more people like this in science.

Appreciate you doing whatever you can to avoid allowing Google ads. Realize it’s not free or easy to write, produce and present your incredible videos. But maybe there’s other ways to allow us to sufficiently support your work besides awful and disruptive advertising. You two are maybe the best teachers I’ve ever seen. Your positive energy and catch phrase “Let’s do this!” is genius. I hope you guys are here for the long haul, keep making videos and remember just like the donor bodies, your content keeps giving back to the world.

"I see you're an organ donor." Damn, my stomach has a better shot at being a RU-vid star than I actually do.

"Here's a double double from In&Out with no pickles or onions because that would be disgusting, and here we have a human stomach turned inside out"

The anatomy and physiology of the stomach has always fascinated me. It contains an acid with a pH so low, that without a thin lining of cells and mucous, the acid would eat through the organ itself. Seeing the effects of NSAIDS and how they inhibit this protective layer is a good common example of a stomach being eaten by its own acid.

13:58 “the thing I’m most nervous about…” *almost knocks over bottle of incredibly concentrated hydrochloric acid*

Thanks to the person that gave their stomach for this 🤞🏽🤞🏽

This is so much more interesting than my biology class in school.

As someone who is studying chemical engineering and works constantly in labs, seeing and understanding everything he did brought a smile to my face, been a fan of science since been a toddler

We appreciate you and all the human anatomy content you put up for us.

Made me realise if only we had good passionate teachers like him to teach us such subjects, id actually understand what im studying because this is highly fascinating!!

As educational and entertaining this video is, I can’t get over the fact that’s there are bodies behind him. Not disturbed but makes life all the more real.

You are absolutely amazing guys! I so much love what you do and how you are presenting it to us, the viewers. I feel lucky that you make this channel and also fell very thankful as all that knowledge, equipment, and everything come with a cost that you have paid (sleepless nights, family separation, lack of time, perseverance push, and so on). I sincerely and deeply thank you!

Okay ngl or exaggerate anything but today, after all these years of studying chemistry & biochemistry in school, I've got a clear understanding of the basics of molarity and that too in just a few seconds! Also, I've recently discovered your channel and loving EVERY video and your concept clearing ability!

Very impressed with this presenter! He is clear, articulate, obviously knows his stuff, doesn’t dwell or labor a point too long, and has an uncanny ability to answer all the questions I wish I could ask if I just keep watching. What more could you ask from a presenter?

what i like about this guy is he seems genuinely happy teaching us how every part of our body works. salute

I wish I had a gastroenterologist as enthusiastic about helping me and my gastritis and ulcers I've had for over a year as you are about teaching and learning anatomy and pathology

Now show us what happens when we swallow a battery

My stomach's tickling

I’ve taught myself so much more outside of school than I ever learned in school.

I never understood biology clearly in my school days... But i fully watched this video... because of how cool this man demonstrating with pretty good accent..... Loved your channel

Taught me more than my school did. RU-vid is an awesome place to be.

Disclaimer on behalf of this channel: Not all gloves are created equally either, don't go thinking random gloves are going to protect you against everything.

All of my life I thought the acid is to break down the food into even smaller bits. ...and I had biology in high school for 9 years. Lol. I feel dumb now.

It's hard for us to wonder if we don't have any visual representation of something. It's a good thing IHA doesn't only provide visuals but there really is a clear and in-depth explanation that makes us understand even better.

I was so engrossed in this video. I enjoyed it so much. If I was his student I am sure biology would be my favourite subject.

Imagine if someone ever told you that your stomach would be laying on top of someone else's while being recorded for a video someday. It's mind blowing

Wonder if it would burn through the floor like in the movie 'Alien'?

i love he does not only do experiments which is the main focus of this video but does silly little experiments outside the main focus of the video out of curiosity which sparks in curiosity in me and thats an amazing thing it was an amazing experience to watch this video!

I've been browsing RU-vid for 14 years. You are the first video that i ever liked. It's clear why your in the medical field. Your curiosity to learn is apparent. You touched on every single point and angle that i was inquisitive about when it came to hydrochloric acid. Thanks for the video. And yes i fell asleep during the math part and when i woke up i continued the rest of the video

The sentence "no pickles or onions because that would be disgusting" followed by "and here is a human stomach turned inside out" is simply brilliant

Its the enzymes in stomach that breakdown the food, the stomach acid is there to provide a optimum condition for the enzymes to work in. - a biology student :)

Anatomy is so interesting. I used to study medicine and I remember a lot in your videos. Thanks for such great lessons!

Sooo educational! Thank you Sir!

He made a nice, informative, friendly presentation! Not easy to do in a room decorated with actual dead bodies.

Speaking of food and digestion. It'd be interesting to see a breakdown of what happens in your body when you eat spicy food.

I love this, i randomly stumble on this video and it was so interesting that i stayed till the end, i am learning more from youtube than school

Thanks for making it educational and super funny at the same time😂

Having acid reflux, let me tell you, it feels like you swallowed a glass of pure acid in your esophagus. It is very painful and causes me to cough so hard and wakes me up from a dead sleep. So grateful for medication.

I'm in a less than ideal spot financially; I am no longer in high school. But these educational videos assimilate knowledge for me in a way that's entertaining and helpful for me to retain. Thanks for showcasing the demonstration that I can't get from school, I'm glad to learn anatomical science here.

I've just met your channel like a week a go and have been procrastinating to watch my first video, and oh boy that's fu#king interesting, I'll watch some other videos and try to support you guys as much as I can. Thanks for making educational content of quality on this platform.

This is so cool and interesting. I love this guy's passion for Anatomy and science in general.

Just casually saying a human stomach turned inside out is the best thing I've heard today snd nothing will top it.

As a SEVERE GERD sufferer, it's amazing to see how little hydrochloric acid is truly in our stomach acid. It feels so much higher when it's burning away in places it doesn't belong. My GERD was so bad and improperly treated for long enough I now have a ton of scar tissue in my esophagus and have to go in for dilation every couple of years. They get it all stretched out laparoscopically with a balloon and it's an immediate difference. I know it's time to go back when I start feeling like things are getting stuck in my throat/I start choking while trying to swallow. While I know it's actually further down that the food is sticking, it's so interesting the brain tells us it's in the throat. First I can't swallow proteins, like chicken, steak, turkey, etc. The next phase is breads, pasta, etc. When I am ready to go in for the procedure, I can barely swallow my own spit and other plain liquids. It tends to happen in a quick succession... Like a couple of weeks. Due to the scar tissue and damage, I'm at high risk for Barrett's Esophagus and esophageal cancer. Hopefully proper treatment the last few years will prevent anything like that. If you are having issues with heart burn and/or reflux and it's not clearing up quickly with OTC products, PLEASE get to your doctor! They can refer you to a gastroenterologist yo get yourself checked out. It usually involves an Upper Endoscopy, which is absolutely NO big deal. The worst part for these types of treats is the prep.l

I love your channel soo much because it enlighten me even more or Thoug am a medical practioner /mua, but this breakdown here is everything to me thank you very much.

Thanks for this. Seeing experiments like these in the real world make the learning experience so much more engaging.

Never ask: A woman, her age A man, his salary *Johnathan, where he got his stomachs*

One issue with the meat in the stomach acid... when it’s in your stomach it is chewed and therefore has a much greater surface area. This will make meat of the same volume dissolve at a faster rate.

The whole video was very interesting, entertaining and educational. Awesome job!

Now im starting to understand Nursing with this presentation! Thank you so much! I’m just new in your channel but it helped me understand human anatomy piece by piece! Thanks a lot! Please keep providing information like this! 🥰

"No pickles and onions, that'll be disgusting" I'm dying of laughter!

Important safety info: when diluting hydrochloric acid, always put the acid in water and never the water into acid!! The dissociation of H+ and Cl- ions in water is a highly exothermic reaction (it produces lots of heat) which can evaporate water if the water is in small quantity (when you just started pouring). If you pour the water in acid, this can bring hot acid droplets onto you! Be very careful and always take safety measures like gloves and goggles, like this gentleman here. Great material, by the way! ;)

Fantastic overview! The rugae were strangely satisfying to see in the hands.

This absolutely makes sense! The stomach acid isn't designed to obliterate anything you eat. It's designed to break down the proteins in food and make your food easier to digest. If it obliterated your food, then that's counter productive because your food would be gone. Edit: just got to the end and I literally just said what you said. LOL great video!

I'm in nursing school and these videos are amazing. They help me understand what's actually happening in the body when we have certain conditions and will hopefully allow me to explain things better to patients once I graduate.

Thank you so much ❤️ for your amazing work Sir,I learn a lot of things about human anatomy from your videos, wish you all the best 👍👍🙏

I learned more watching this vídeo than my 6 years in school, keep up the good work 👍

when he showed what the stomach looked like cut open, i thought, “That’s some Menudo right there” 😭

As an Italian I’m always amazed to find out pretty much every name used in anatomy is in fact an Italian word some of them still used in modern Italian

Thanks bro for performing this experiment. U cleared some stereotypical thought many of many audiences obout HCl

I've watched a lot of your videos and this one was the most interesting so far.

He is actually teaching me what I had forgotten during chemistry class of my pharmacy school.

I felt so anxious when he lifted the tray with the open bottle of acid

This video teaches me things that answer my questions, love the work thanks!

Your content is very appreciated! Thanks for the knowledge!

"No pickles or onions because that would be disgusting" *He says with a human stomach laying centimeters away from the sandwich*

My finger when I dip it in water for 1 minute: 2:07

absolutely amazing video and question answering experiment👍👍👍

Guys trust me it's brilliant network for learning and the way of explaining is amazing Thanks for such a informative network on RU-vid ❤️🥰

The guy who got their body parts removed for this video is a legend. Or *WAS* a legend at least.

One of the most scary things I have ever experienced, was being suddenly waken out of my sleep, taking deep gulps of air, feeling like I was being suffocated with this strong burning sensation in my upper chest. My initial thought was that I was suffocating somehow, and so I was literally *heaving* breaths trying to get it under control. Took about half a minute for me to realize just what had happened, when I noticed the taste -- stomach acid had crept up the esophagus and into the lower throat and the pain of it tricked me into thinking that there was something wrong with my lungs and my body responded by taking in huge breaths of air and also triggered the fight-or-flight reflexes as well as waking me out of sleep. Thankfully that has only happened to me like 2-3 times and the second time and beyond, I recovered quicker because I know exactly what it is now. The first time was damn scary, though.

For those with frequent heartburn, I would recommend seeing a GI doctor to get it under control and prevent damage to the esophagus. I was diagnosed with Barrett's Esophagus this year at age 29. In my case, for the rest of my life I have to take a type of medication called a PPI (proton pump inhibitor) that reduces the amount of stomach acid produced. Although a small percentage of Barrett's patients get cancer, it is still a higher risk. Fortunately, there are procedures that can be done to lower the likelihood that it progresses to cancer.

I love these shows. Neat to see what's inside my body. Thank you guys.

him: imma lay these stomachs on top of each other both of them watchin from heaven : 👁️👄👁️

Thank you so much for your hard work and for making this video!!! it really helps to learn new facts about our human body

I’m mesmerized, I could listen to this for hours

16:30 great video to show the importance of emphasizing chewing as part of the digestive process. Kids should see this experiment. Good job.

I taught high school biology and human anatomy/ physiology for 30 years.. This program brings back lots of wonderful memories but also a lot of the absolute terror of doing labs with potentially hazardous materials and fire with 30 teenage kids with inquiring minds 5 times a day. Lab preparation on my part was geared toward safety as well as scientific inquiry all within the context of what could possibly go wrong. I was lucky…no major incidents except for one slashed hand and a 50 gallon fish tank broken and spewing water into the classroom. I feel like I got off easy.🤗

i love how they get so serious when they are talking about anatomy, you can tell they love what they teach!

I've no qualifications in medicine, anatomy or even science. I was discouraged from doing chemistry at a higher level by my school & parents because I was a girl. 😠 But I've always been fascinated. I can't get enough of this series. It's fantastic & easily understandable for someone who last studied sciences as a 16 year old in the 80s, apart from an in-depth MOOC in nutrition offered by Stanford a few years ago. Thank you for doing these videos. 🙂

Great presentation! I think Anatomy is fascinating. Not in the medical profession but regardless what you show is in great detail and in good taste. I even found an excellent app (wasn’t free!) for my phone. Learned a lot!

Your math lesson took me back to being in high school chem class. I always loved doing conversions.

hi this video is great and I love this educational content .However, there is a wrong fact at 5:51 you said that the increase of acidity between ph 7 and ph2 is 50 times due to the fact that the difference between ph7 and ph6 is 10 fold but, the ph scale is logarithmic meaning that the difference between ph7 and ph2 is ten to the fifth power not ten times five. However I do not wish to criticise this channel as I love your content.

if my bio classes were this interesting i'd actually understand stuff

Thankyou for providing such informative content ❤️❤️

If my biology teachers had explained things as well as you guys do I would have been a doctor. So interesting. Your presentation and respect of the donated organs is to be admired. Thank you

7:24 “No pickles or onions because that would be disgusting” he says with the inside of a real human dissected stomach in front him

This was very interesting. I would like a part 2 of this video where you guys discuss the enzymes involved in food digestion. I am lactose intolerant, lol where did my lactase enzyme go?😅

casually watching this while eating my breakfast really shows a lot about me i feel like. as someone with several GI diseases this is so fascinating

I was a lab assistant in college doing prep work. You're taking me down memory lane on molarity, normalization etc...lol.

Does the "pseudostomach acid" have a required temperature ? since our inside of our body or our body is warm . does the temp. would make it a difference ?

It eroded all of my back teeth from both pregnancy and Crohns related vomiting for years. If my doctors had told me to rinse my mouth with a baking soda solution after throwing up I probably wouldn’t have lost those teeth!! That acid is no joke 😳

I wish you guys would do a video on the effects of spicy peppers on the stomach. Start with Jalapeños and end with ghost peppers. I love spicy food and everyone always says that peppers damage the stomach and cause ulcers. I know that ulcers are usually caused by bacteria, not peppers. It’s just a thought…love the videos and teaching!
