Learn. The role of the immune system is to protect and defend the body against infectious diseases. The immune system is broken into two branches, the innate immune system and the adaptive immune system. The innate immune system is a general immune response which is not specialised to fight against a particular pathogen. A pathogenContinue reading “The immune System – HSC Biology”
