Explanation:
Detailed explanation-1: -Innate immunity can be viewed as comprising four types of defensive barriers: anatomic (skin and mucous membrane), physiologic (temperature, low pH and chemical mediators), endocytic and phagocytic, and inflammatory.
Detailed explanation-2: -Phagocytosis is an important and effective mechanism of destroying pathogens during innate immune responses.
