Detailed explanation-1: -The second line of defense are the non-specific phagocytes and other internal mechanisms that comprise innate immunity. The third line of defense are the specific lymphocytes that produce antibodies as part of the adaptive immune response.
Detailed explanation-2: -The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
Detailed explanation-3: -The immune system’s three lines of defense include physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
Detailed explanation-4: -What is the body’s third line of defence against pathogens? The third level of your immune system consists of cells tailor-made to get rid of the specific microorganisms that have invaded your tissue. Special cells called dendritic cells are the liaison (point of communication) between innate and adaptive immunity.
