The immune system

Our organs are the part of our bodies that help us to do things, like the brain that thinks, or the heart that sends blood around our bodies. The immune system comes from the cells and organs that work together to protect us from diseases.

The immune system does this by destroying things that get into our bodies like viruses. A virus is a very, very small thing that causes a disease. The disease could be something ordinary, like the kind of cold we all get sometimes or it could be something serious like the covid-19, which first appeared at the end of 2019. when a virus gets into a part of the body, a message is sent to the immune system. Then the immune system reacts by sending cells to find the virus. cells are the smallest, separate living things in our bodies and they are small enough to fight against a disease

Some people's immune systems work better than other people's. we all want our immune systems to be strong so we can stay healthy, so what can we do to help? We can boost your immune system by eating a lot of fruit and vegetables, especially vegetables with green leaves. You also need to exercise regularly. We don't have to run 50 km every day but we need to be as active as possible. We also need to make sure that we get enough sleep. for most people that means at least 7 hours every night. Finally, we must do things like washing our hands regularly, which will help us to avoid getting a virus or an infection in the first place. We also need to do things like covering our mouths when we cough to stop other people getting an infection or virus.
