Quizplus · Accepted Answer

Protective proteins (such as complement proteins), the epidermis (as a physical barrier), phagocytic cells (such as macrophages), and neutrophils (a type of white blood cell) are all examples of innate immunity, which provides immediate defense against pathogens without prior exposure or stimulation. Active immunity, on the other hand, results from the body's response to a pathogen or vaccine, while secondary immune reactions refer to the memory response of the adaptive immune system. Immunopreventatives and antigen stimulators are not commonly used terms in immunology.
