The stomach plays an important role in the body. It breaks down food so that nutrients can be absorbed. Its size even changes to accommodate food. The stomach does so many interesting things. Here are some facts about the stomach:
There is no association between heaviness and stomach size. A thin person can have the similar size stomach, as a person who is heavy. An adult’s stomach can grasp as much as 1.5 liters of food.
The stomach serves as a first line of defense for your immune system. It contains hydrochloric acid, which helps to kill off microbes that may be in food.
When you blush (when your face turns red), the lining of your stomach also turns red.
People can, and have lived without a stomach, if it has been removed because of disease.
The stomach produces mucus. This prevents the stomach enzymes from digesting the stomach walls.
The stomach is not where all the digestion of food takes place. The small intestine is where most of the food is digested.
When you eat, the food doesn’t fall through your esophagus and into your stomach. The muscles in your esophagus contract and relax in a wavelike manner called peristalsis. This pushes the food down through the small canal and into the stomach.
Stomach rumblings are caused by peristalsis. This occurs at the walls of the stomach and small intestine. These are normal digestion movements. It is louder and more noticeable, when the stomach is empty.
The stomach passes on a thick liquid called chyme. Enzymes continue to break chyme down in the small intestines.
Stomach acid is corrosive enough to eat through metal and bone. It is the same acid used in factories, to strip rust off steel and iron. Your stomach makes up to 3 liters of acid every day.
When you swallow food, you also swallow air. This air causes most of the gas in your stomach and intestinal tract. The best way to get rid of it is to burp.
Your stomach is attached to the end of the esophagus. It is a stretchy sack that shaped like the letter J.
