Detailed explanation-1: -Skin, tears and mucus are part of the first line of defence in fighting infection. They help to protect us against invading pathogens.
Detailed explanation-2: -Keratinocytes. Keratinocytes are the predominant cells in the epidermis. They act as the first line of innate immune defence against infection.
