(B) The human body has innate immunity which provides different types of barriers to prevent the entry of foreign agents. $1$. Physical barriers: These include the skin and the mucus coating of the epithelium lining the respiratory,gastrointestinal,and urogenital tracts. These barriers trap microorganisms and prevent them from entering the body. $2$. Physiological barriers: These include acid in the stomach,saliva in the mouth,and tears from eyes,which prevent microbial growth. $3$. Cellular barriers: These include leukocytes like polymorphonuclear leukocytes ($PMNL$-neutrophils) and monocytes,and natural killer cells in the blood,as well as macrophages in tissues. $4$. Cytokine barriers: These include virus-infected cells which secrete proteins called interferons that protect non-infected cells from further viral infection. Therefore,the mucus coating of the urogenital tract is a physical barrier.

The mucus coating of the lining of the urogenital tract helps in trapping microorganisms entering our body. Which type of barrier is this?
