Vedclass · Answer

(A) Innate immunity consists of four types of barriers: physical,physiological,cellular,and cytokine barriers.$1$. Cellular barriers include cells like Polymorphonuclear leukocytes ($PMNL$-neutrophils),monocytes,and natural killer $(NK)$ cells that phagocytose or destroy microbes.$2$. Antibodies are part of the acquired (adaptive) immune system,which is produced by $B$-lymphocytes in response to specific antigens.$3$. Therefore,antibodies secreted by lymphocytes are not part of the cellular barrier of innate immunity.
