When you think about the inside of the body, you probably think about blood flowing, the vital organs and some of the things that could go wrong if you’re sick or injured. One of the things that you might not think much about is the stomach and digestive system. It’s on your mind when you’re eating or if you experience nausea or vomiting, but other than that, it’s usually an area of the body that doesn’t get a lot of attention.
The stomach makes a new lining about every three days. It does this so that it doesn’t digest itself while processing the food that you eat. Hydrochloric acid is a substance that is present in the stomach to help with digesting your food. It’s also a substance that is used to clean or treat metals. Even though the acid is very powerful, the lining of the stomach keeps it from eating away the digestive system and entering the rest of the body. Therefore, the lining is made repeatedly. If it wasn’t reproduced on a regular basis, it would begin to break down, which could mean that the acid would start to leak outside the digestive system and into vital areas of the body.
