Facts About The Human Digestive System
Every single living being on this planet goes through a process called digestion. Every time we consume a meal, it immediately starts to go through the process of digestion, which is the process of breaking down your food and turning them into tiny pieces that can move on through the bloodstream to turn into energy. Some people don’t realize this but human digestion is a big process and not everyone knows about it, so here are some fun and interesting facts you might find useful.
Your mouth has a neutralizing role
Your mouth, as part of this process, is around to make your food cooler and or warmer to make it easier for the digestive juices to pour on through to the small intestines.
Daily saliva production
We produce about 1.7 liters of saliva every day we live. Our nervous system takes full capacity over our saliva. It is that system that makes us feel cravings when certain foods are brought up.
Peristalsis can defy gravity
Our digestive tracts are around to help us push our food through. There is a certain muscle that outlines the digestion organs and they bond in a pattern, this pattern can be referred to as the peristalsis, which is the act of forcing food down into the tract. Even if you’re upside down for any reason anything you consume will go toward your stomach no matter what.
The human stomach is attached to the esophagus at one end and the small intestine on the other end. The picture above shows the detail structure of the human stomach and the tissue structure.
Stomach capacity is huge
Our stomachs can not only get huge themselves but they can store about 1 liter of our everyday foods. Although, unhealthy, our stomachs can store up to four times the amount of food that smaller creatures couldn’t.
Small intestine plays a significant role in our digestive system. It is filled with millions of small tubes called villi. The purpose of villi is to increase the effective, absorption surface area by 60 times.
Small intestine is at least 20 feet long
Once it’s gone from your stomach, the slightly digested food, referred to in this instance as Chime will go into your small intestine. That food will run into a monster down there at 3.5 times our actual body length. Considering how tall it is, it has to be divided as three different parts. There’s the duodenum and then it moves onto the jejunum and finally we have the ileum.
Villi actually increase the surface area
There is a small projection, the size of a human finger by the name of the Villi. The Villi are the little things responsible for increasing the size of the small intestines to about 250 square meters. That’s pretty big. This will in turn let the small intestines absorb all the broken down particles.
Large intestine is much shorter than the small intestine
Here’s a bit of irony, the large intestine is actually smaller then the small intestine. The large intestine is just at the length of five feet, the small and large word has nothing to do with the sizes of these organs, it is purely based on the width of each organ’s tube.
Large intestine and colon aren’t the same thing
Our large intestines and the colon are often times mistaken for the same thing, that isn’t the case though; the colon is actually a part of the large intestine and performs its own duties. So in reality, the colon is just one factor about the large intestines.
Flatulence has several little-known factors
What scientists refer to as “intestinal gas” is what we would refer to as “farting”. This is caused by our stomach as bacteria begin to enter our digestive juices and that’s their way of evacuating the tract. It contains abundant gas sources such as carbon dioxide as well as hydrogen and finally some methane gas.
Noise from passing gas is not related to vibration
No, vibrations are not the cause of passing gas. This noise is made when your natural gases goes through what is known as the anal sphincter. The noise is created based on the amount of gas, the power and tightness of how it goes through the sphincter.
