| List – I | List – II |
|---|---|
| (A) Physical barriers | (I) Acid in stomach, saliva in mouth and tears in eyes |
| (B) Cytokine barriers | (II) PMNL-neutrophils and monocytes |
| (C) Cellular barriers | (III) Skin on body, mucus coating of epithelium which lines respiratory tract |
| (D) Physiological barriers | (IV) Interferons |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
(A) Physical barriers — this matches (III) Skin on body, mucus coating of epithelium which lines respiratory tract. They stop microbes from entering.
(B) Cytokine barriers — this matches (IV) Interferons. Virus-infected cells secrete them to protect other cells.
(C) Cellular barriers — this matches (II) PMNL-neutrophils and monocytes. They engulf microbes.
(D) Physiological barriers — this matches (I) Acid in stomach, saliva in mouth and tears in eyes. They kill or wash away microbes.
