Inflammation and wound healing (chapter 14), immunity (p. 287- 305) Defence: the body protects against invasions by microorganisms and prevents the development of infection by attacking foreign antigens and pathogens. Homeostasis: damaged cellular substances are digested and removed, through this (cid:373)e(cid:272)ha(cid:374)is(cid:373), the (cid:271)ody"s differe(cid:374)t (cid:272)ell types re(cid:373)ai(cid:374) u(cid:374)ifor(cid:373) a(cid:374)d u(cid:374)(cid:272)ha(cid:374)ged. Surveillance: mutations continually arise in the body but are normally recognized as foreign cells and destroyed. Innate immunity: exists in a person without prior contact to an antigen. This type involves a nonspecific response: neutrophils and monocytes are the white blood cells primarily involved. Innate immunity that is not antigen specific is the type present at birth. Acquired immunity: the development of immunity, either active or passive: active acquired immunity: results from the invasion of the body by foreign substances such as microorganisms which leads to the development of antibodies and sensitized lymphocytes.
