Vedclass · Answer

(A) The correct matches are as follows:$1$. Physical barrier: The skin is the primary physical barrier that prevents the entry of microorganisms into the body. Thus, $(a-y)$.$2$. Physiological barrier: Acid in the stomach, saliva in the mouth, and tears from eyes prevent microbial growth. Thus, $(b-w)$.$3$. Cellular barrier: Certain types of leukocytes (WBCs) like polymorphonuclear leukocytes ($PMNL$-neutrophils) and monocytes are examples of cellular barriers. Thus, $(c-z)$.$4$. Cytokine barrier: Virus-infected cells secrete proteins called interferons which protect non-infected cells from further viral infection. Thus, $(d-x)$.Therefore, the correct sequence is $(a-y), (b-w), (c-z), (d-x)$.
