How Your Digestive System Fights Pathogens
Ғылым және технология
Our digestive system does a lot more than just break down food for us. It actually has a role in our immunity. In this episode, Patrick explores how immune system checkpoints within the digestive tract protect us from pathogens.

There’s a long and winding canal that goes from our mouths to our anuses called the alimentary canal or sometimes the gastrointestinal tract. This tube starts and ends outside of your body, and it’s how you process and extract nutrients and materials from the food you eat. But it’s also a spot for potential pathogens to sneak in.
Our digestive system interfaces with all kinds of nasty germs, and as a result, it’s armed with multiple immune system resources to protect our insides from the outside.
Digestion itself is a long process and involves everything from mechanically grinding down food in our mouths to treating food with enzymes so that we can absorb the nutrients better. Therefore, there isn’t just one immune system checkpoint - there are safeguards along the entire system.

Introduction to the Digestive System
training.seer.cancer.gov/anat...
“The digestive system includes the digestive tract and its accessory organs, which process food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated.”
Physiology - Digestion
www.ncbi.nlm.nih.gov/books/NB...
“Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins. Through the process of digestion, these macronutrients are broken down into molecules that can traverse the intestinal epithelium and enter the bloodstream for use in the body.”
Immunity in the Gut
www.immunology.org/public-inf...
“The large intestine (colon) has a large resident population of microbiota, consisting of at least 1012 organisms per gram of luminal contents. These organisms, together with the antigenic load provided by the diet and the constant threat of potential pathogens, means the intestinal immune system encounters more antigen than any other part of the body.”

Host and writer here. Did any of y’all see that episode of the Magic Schoolbus where they shrink down and go through that kid’s digestive system?

How do you know when your digestive system has failed to protect you from pathogens? You just have a gut feeling.

Gut can be revitalized by using only organic foods, complete no to processed foods, organic fruits, drinking red wine in certain doses, yoghurt, sprouts, vegetable salads
No wonder stomach viruses are so short lived; with all these immune systems, as well as vomiting and diarriah, we get the germs out fast.
Can you talk about what happens when your immune system goes awry in your gut AKA discuss Chon's and Ulcerative Colitis.
So having my appendix removed has had long term effects… Great, not only did I have the problem that it was imploded instead of the regular exploded. And it was removed with just a few hours to go before 💥, so they removed some of the surrounding tissue as well. All in all this is a design flaw…
When I was a youngin in school, they asked the class where food went after it went into your stomach. I answered 'blood'. And they agreed. Now I understand that they were looking for another, a lot more smelly answer lol. They didn't expect my response.

How close are they to knowing what causes ulceritive colitis? After seeing this video, I would think they would know the cause by now, but I don't think they really do yet.
Hi, you have a wonderful way to explain and make understand how things work in our body. I am wondering if I can you make a video explaining how the digestive system is damaged for gastroparesis due to diabetes and it would be possible to reverse?
Amazing and well explained thank you
Tell Homer Simpson he's a long donut - then he'll eat himself lol !

This is great. It'll be even better if it's made simpler for a common with little technical knowledge as there seems to be a lot of words thrown at me and I retain lesser. Great effort though thanks.
And I’m watching this with a stomach bug 😞 there are some things our wonderful alimentary canal can’t fight.
This needs a more in depth detail video, or better yet a hole series, in wich, each portion has its own episode.
I don't like the thought of being referred to as a long donut lol

Gut microbiome and appendix play role in innate immunity.. interesting🤩🤩 want to know more....
I'm relieved that you showed someone's mouth without any tonsils in it
2:25 looks like pieces of corn. Which looks the same coming out, as going in.
Honestly, I expected a lot more when I read the title..even someone going to school will know all these things
So, If we get our appendix removed, will we not lower our immunity?
Accurate
I’m a Krispy Kreme walking donut.
Wow
Fun fact, I get frequent cold sores and no joke, French kissing my wife helps them heal faster. She hardly ever gets them, so I think there is some definite immune system boosting going on 😉

just like many other seeker videos, this video is too quiet
he just had to say it didnt he.
The whole message, holography, in the big picture, is restricted to understanding aspects of real-time Infinity, and some aspects are Scientific Categorization of Superspin Modulation positioning function cause-effect in Actuality-Singularity Perspective, in e-Pi-i Principle, so it's stratified focal matricies of Quantum Chemistry atomistic arrangements of pure-math ideal gas of time-timing sync-duration recirculation, and according to Documentaries on UCTV, our biological integration of Predator-prey balance included in bodily defences is an unexpectedly fine balance of pathogens and general ecology of life somewhat similar in concept to the Anthropic Principle Imagery projection-drawing composed of Holographic AM-FM Communication In-form-ation alignments. It is not what I expected to think of about what, how and why things happen as they do in continuous creation cause-effect connection. E=mC² logarithmic condensation wave-packaging formation is Quantum Chemistry, and fundamental to Be Here Now holography dimensionality coordination shaping. One should not be surprised, but also the wonder of Sciencing Re-search is surprising that there is no actual limit on things to learn.

As long as you have a clean mouth, then you should be fine. Saliva also has blood coagulants to help start the sealing/healing process. I've heard in a country in South America, they have a believe that you should have a pregnant woman spit on it, which scientifically has been shown to have a higher concentration of coagulants and antibacterial properties. 😅
