OUR IMMUNE system is made up of many different organs which contribute to our immunity. Our skin prevents pathogens from entering our body while various internal organs (including bone marrow, spleen and lymph nodes) produce cells and antibodies that specifically target pathogens.
The digestive system helps defend against pathogens entering via the gastrointestinal tract. The digestive and immune systems work together to signal immune cells.
