Question

Quizplus · Accepted Answer

Adaptive immunity is a specific defense mechanism that targets a particular pathogen, creating a memory of that pathogen for future encounters. Innate immunity provides a general defense mechanism against any pathogen, physical barriers such as skin and mucous membranes, and several cellular and molecular defensive responses. Immunological surveillance is the process of identifying and destroying abnormal cells in the body. Skin defenses and fever are part of the innate immune system. Therefore, the best choice for providing defense against a particular pathogen is adaptive immunity.
