The immune system helps fight off attacks from ‘foreign invaders’, the immune system is a network of cells, tissues and organs that help fight off attacks from viruses, parasites and micro organisms that enter our bodies that can cause infections and other problems. The idea that all the cells in our bodies have codes ‘tattooed’ onto them that are unique to each of us help us understand what the immune system does clearer. Whenever micro organisms ect, enter our bodies and don’t have our individual codes on them the immune system seeks these out and destroys them our bodies remember these and will make the us immune to them if they ever enter our bodies again.
