MCQ
Match the following columns and select the correct option
Column $I$ Column $II$
($a$) Pneumotaxic Centre ($i$) Alveoli
($b$) $O _{2}$ Dissociation curve ($ii$) Pons region of brain
($c$) Carbonic Anhydrase ($iii$ Haemoglobin
($d$) Primary site of exchange of gases ($iv$) $R.B.C.$
  • A
    $(a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)$
  • B
    $(a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)$
  • $(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)$
  • D
    $(a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)$

Answer

Correct option: C.
$(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)$
c
The correct answer is option (3) because pneumotaxic centre is present in the pons region of the brain.

In $O _{2}$ dissociation curve, percentage saturation of haemoglobin is plotted against the $pO _{2}$. Carbonic anhydrase is mainly present in the RBCs and its minute quantity is present in the plasma.

Alveoli are the primary sites of exchange of gases.
