309 - What is the role of bacteria in our bodies?

Bacteria play many helpful roles in our bodies. Some of their important tasks include:

  1. Helping us digest food: Good bacteria in our stomach and intestines break down food so our body can get the nutrients it needs.
  2. Keeping us healthy: They produce special helpers called vitamins that keep us strong and healthy.
  3. Fighting off bad germs: Good bacteria can help fight off bad germs that can make us sick.
  4. Helping with skin and gut feelings: They can even affect how we feel and think by making special chemicals that help us feel sad or happy.

So, bacteria are like tiny superheroes that live inside and on our bodies, helping us stay healthy and strong!
