IMMUNITY

Immunity, the body’s defense against pathogens, has fascinated humanity for centuries. From ancient perceptions of disease as divine punishment to modern scientific understandings, the concept has evolved significantly. This book delves into the nature of immunity, explaining both innate and adaptive immune responses. Innate immunity provides immediate protection through barriers and phagocytic cells, while adaptive immunity develops over time, involving specific responses by lymphocytes. The text covers both humoral and cellular immunity, as well as the dynamics of passive and active immunity. Through this, the book offers a comprehensive overview of immune system functions in health and disease.
