The immune system comprises: physical and chemical barriers; the non-specific immune mechanisms, which bring about inflammation; and the specific immune system, which recognises and memorises foreign antigens [see glossary on page 55]. The immune system depends on white blood cells that play a key role in protecting the body from invasion by pathogenic microorganisms, infection and disease, particularly cancers. Disorders or disturbances of the immune system can leave the patient vulnerable to infection.
