There are always lots of nasty bacteria and viruses around us but we have a very effective internal defense mechanism called the immune system. Special cells are spread throughout our bodies and when potentially harmful bacteria or viruses hit us, the cells send a warning signal to the other parts of our system to take care of it and prevent the sickness from spreading. So an immune system is practically a network and does an amazing job of protecting us. For that reason, we should be looking after it and taking better care of ourselves.
