Your Immune System
So it makes sense that the body system that helps fight of sickness is called the immune system. The immune system is made up of network of cells, tissues, and organs that work together to protect the body.
Healthy kids can help their immune systems by washing their hands regularly to prevent infections, eating nutritious foods, getting plenty of exercise, getting enough sleep, and getting regular medical checkups.
And if you feel gerat today, THANK YOUR IMMUNE SYSTEM!
