Our immune system is made of different organs, proteins, cells, or chemicals that can work together to help defend our body from outside invaders. We can separate the immune system in two: one is the innate immune system which is the one we were born with. The other one is the adaptive immune system that could learn and develop over time. There are many other ways to define or classify our immune systems. Our lifestyle can also have an impact on our innate immunity.
