In: Biology

The intestine wall can get infected by the bacteria or fungi from the spoiled food. So when contact with spoiled food or some harmful microorganisms is detected, the intestine starts an emergency flush protocol to get rid of everything in it – that is diarrhea. It technically serves the same purpose and works in the same way as runny nose.

Our body has ways to regulate what it wants and doesn’t want inside out body. In terms of harmful things like pathogens or fungi, it does this by sneezing, coughing, throwing up, or diarrhea. These methods are usually crude in terms of sterilizing the body as a lot of bad stuff will obviously be left behind, but it helps a lot. It can mean the difference between the body having to fight hundreds of millions of something and just millions. If we didn’t have these things, our immune system would probably have a really hard time fighting off illnesses and we would probably get sick a lot more often.
