How does my skin protect me from getting sick?
This lesson teaches us how our skin protects us from bacterial infections. A person’s body can become infected from an abrasion/cut, so we must clean the cut and cover it to stay safe and avoid getting sick. We begin with the abstract concept of germs and how they might enter our bloodstream and make us sick.
Understand that our skin protects us from infection. When our skin opens, bacteria may enter our body and make us sick. We protect ourselves by always finding our cuts, cleaning them and covering them.
