Do you think that the brain or the heart or perhaps the human lungs are the most complex organs in a human body? Sorry to break it to you, they aren’t the only super-complex organs we are blessed with. If not totally as equal in complexity as the brain, the human stomach is a very complex organ that is capable of achieving extraordinary feats. So, let us learn 30 interesting human stomach facts and find out what this organ is capable of.
Interesting Human Stomach Facts: 1-10
1. One of THE MOST interesting human stomach facts is that it is fully expendable. Simply put, if the stomach is removed, a person can survive. You must be wondering, if the stomach is removed, how the hell is the food digested?
2. This brings us to our second point. It is a total myth that the stomach is responsible for digesting food all the food. We have been taught wrong in our schools. Only partial digestion takes place in stomach. The rest of digestion is carried out by our small intestine. The stomach only aids the small intestine by breaking down the consumed food in smaller pieces.
3. So, once a stomach is surgically removed totally in a process called Total Gastrectomy, the surgeons end up attaching the esophagus to the small intestine directly. So, whatever you consume goes to the small intestine, where it gets digested. Only this time, the small intestine needs to work really hard because the stomach is no longer there for breaking down the food into smaller pieces to aid digestion.
4. This means that a human is capable of retaining his full-blown digestive system even without the stomach. That’s one hell of a super power of humans. Isn’t that one of the surprisingly awesome stomach facts?
5. So, what really the does sitting there in between the esophagus and the small intestine? It does a lot of thing. It is the first defence the body puts forward against any type of harmful microbes that enter our body with the food we consume. The stomach produces acid, which tries to eliminate those microbes.
6. What kind of acid? You might get a shock! The stomach produces industrial-grade concentrated HCL or hydrochloric acid which eat through bones and metals. This means that if you put a drop of your stomach acid on your palm, it will melt your muscles, your bones and your skin to go right past out the other side.
7. So, if that acid is so corrosive, why the hell is it not dissolving our whole stomach and then other organs? Good question! The answer to this question is very complex but we will give a very simple explanation. Inside our stomach is a layer of mucus membrane layer known as the mucosa. This mucosa has two types of cells – the parietal cells and goblet cells.
8. The parietal cells are the once that produce the acid. The goblet cells are once that produce very large quantities of mucus, which covers the entire mucosa. This mucus is immune to acidic corrosion and hence, the stomach itself remains immune to the corrosive HCL.
9. So, how much of this acid is produced in our body every day? Can you guess? Okay, it produces 3 liters of hydrochloric acid in a single day. That’s quite a lot!
10. Apart from the two types of cells previously mentioned (i.e. the parietal cells and the goblet cells), the mucosa also has two other types of cells – the G Cells and the Gastric Chief Cells. These cells produce proenzymes. Proenzymes are actually enzymes in inactive state.
