Innate immunity is non-specific and is present before birth. Reference: The first line of defence in a human body against pathogens is through barriers such as the skin, mucus layers, and saliva. Provides effective and long-lasting protection. Eg: Skin is a physical barrier as well as chemical and biological barrier as it produces antimicrobial proteins; Surface lining of the respiratory system has cilia for preventing pathogens and building up of microorganisms; Stomach release strong acids with low pH and kills microorganisms that we accidentally ingest while eating; tears also is an example of barrier immunity as it protects our eyes from dust and pathogens. Following are the important difference between active and passive immunity: Difference Between Active And Passive Immunity.
