Immune system lecture - Study guides, Class notes & Summaries

Introduction to the Immune System Immunity is defined as resistance to disease, specifically infectious disease. The collection of cells, tissues, and molecules that mediate resistance to infections is called the immune system, and the coordinated reaction of these cells and molecules to infectious microbes is the immune response. Immunity is the study of the immune system and its responses to invading pathogens. The physiologic function of the immune system is to prevent and removed infections...
