2020 Phase-2 Breathing and Exchange of GasesRegulation and physiology of respiration Medium Question 21 of 53 in Breathing and Exchange of Gases

Match the following columns and select the correct option:

Column I

  • a. Pneumotaxic Centre
  • b. O2 Dissociation curve
  • c. Carbonic Anhydrase
  • d. Primary site of exchange of gases

Column II

  • i. Alveoli
  • ii. Pons region of brain
  • iii. Haemoglobin
  • iv. R.B.C.

Correct answer: a → ii, b → iii, c → iv, d → i

Solution

Pneumotaxic Centre is located in the pons region of the brain (a-ii); the $O_2$ Dissociation curve pertains to haemoglobin (b-iii); Carbonic Anhydrase is found in RBCs (c-iv); the primary site of exchange of gases is the alveoli (d-i).
