Quizplus · Accepted Answer

The body's first line of defense against infection includes physical and chemical barriers such as skin, mucous membranes, and secretions like sweat. Sweat contains antimicrobial peptides that help prevent infection, making it part of the first line of defense. White blood cells and T lymphocytes are part of the body's second line of defense, involved in the immune response once pathogens have bypassed the first line of defense.
