The immune system can be hard for kids to understand, but kids do understand that people get sick, which is a good starting point.
The immune system is the body’s way of protecting itself against too many germs and other things that can make people sick.
Do You Get Sick a Lot? Doctor Says 'Try This!'
Our bodies have millions of germs in and on them all the time. Normally, germs don’t get us sick, and many even help keep us healthy. But sometimes the germs multiply and there are so many of them that they can make us sick. That’s when the immune system is needed.
The immune system makes special kinds of cells that can attack germs before they can make you sick. These cells can communicate with each other and with parts of your body so that the attack works better,
according to Ducksters Biology for Kids.
Here are some parts of the body that work with the immune system.
1. Your skin makes a barrier against germs getting into the body. It also makes substances that kill bacteria so that you don’t get infections on your skin,
according to Children and Youth Health.

2. Different parts of the brain known as glands send hormones into the body to help it do all kinds of different things like digest food, sleep, and keep its temperature normal. These glands also help the immune system do its job.
3. Your bloodstream contains many of the immune cells that fight against germs. This way the cells can travel to all the different parts of your body where there might be too many germs.
4. A part of your body called the lymph glands acts as a filter for germs,
according to Kids Health. The lymph nodes are on both sides of your neck. Sometimes you can feel them hurting or swelling up when you are sick.
People’s immune systems don’t always work the way they are supposed to. If you get better after being sick and don’t keep getting the same sickness over and over again, your immune system is probably working well. Other signs of a good immune system are getting some swelling around a cut, that the cut heals without getting infected, and having swollen glands (lymph nodes).
