Diagrammatic representation of Lymphatic system.
Match List - I with List - II.
| List - I | List - II |
|---|---|
| (A) MALT | (I) Largest reservoir of erythrocytes |
| (B) Spleen | (II) Provides microenvironment for development and maturation of T-lymphocytes |
| (C) Thymus | (III) Peyer's patches |
| (D) Small intestine | (IV) Lining of urogenital tract |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
(A) MALT — this matches (IV) Lining of urogenital tract. Mucosa-associated lymphoid tissue lies in the linings of the respiratory, digestive and urogenital tracts.
(B) Spleen — this matches (I) Largest reservoir of erythrocytes. The spleen filters the blood and stores erythrocytes.
(C) Thymus — this matches (II) Provides microenvironment for development and maturation of T-lymphocytes.
(D) Small intestine — this matches (III) Peyer's patches. These lymphoid patches lie in the wall of the small intestine.
