Microorganisms are tiny living things that are everywhere, even inside our body. The effects of microorganisms on the human body can be both good and bad.

The good effects:

• They help break down food in our stomach and intestines.
• They help keep our skin and eyes healthy.
• They help our body fight against diseases by making antibodies.
• Some microorganisms are even used in medicine to make medicines and vaccines.

The bad effects:

• Some microorganisms can cause diseases such as cold, flu, diarrhea, and tuberculosis.
• They can infect our skin, eyes, and other body parts, causing inflammation and pain.
• Some microorganisms can even be life-threatening if not treated properly.

So, microorganisms are like having both friends and enemies in our body. We need to keep our body healthy and clean to keep the good microorganisms happy and the bad ones away.
