1.	Name the type of immunity that is present at the time of birth in humens. Explain any two ways be which it is accomplished .
Answer» Innate Immunity is present at the time of birth. Innate immunity consists of four types of barriers : `{:("1. Physical barriers., 2. Physiological barriers." ),( "3. Cellular barriers. 4. Cytokine berriers." ):}` 2. Cellular barriers-Certain types of leukocytes (WBC) of our body like polymorphonuclear leukocytes (PMNL-Neutrophils) and monocytes and natural killer in the blood as well as Macrophages in tissues can Phagocytose and destroy microbes. Cytokine berriers-Virus infected cells secrete proteins called interferon which protect non-infected cells from further viral infection.
