The figure given below shows a small part of human lung where exchange of gas takes place. In which of the options given below, the one part A, B, C or D is correctly identified along with its function.
1 A-alveolar cavity - main site of exchange of respiratory gases
2 D - capillary wall - exchange of gases takes place here
3 B - Red blood cell - transport of \(\mathrm{CO}_{2}\) mainly haemoglobin
4 C-arterial capillary - passes oxygen to tissues
Explanation:
Option (1) is correctly mentioned as alveoli which are the primary sites of exchange of gases. The exchange of gases \(\left(\mathrm{O}_{2}\right.\) and \(\left.\mathrm{CO}_{2}\right)\) between the alveoli and the blood occurs by simple diffusion.

Identify the correct statement.
1 In lungs, gaseous exchange takes place by active transport.
2 The solubility of oxygen is 20-25 times higher than that of carbon dioxide
3 The thickness of diffusion membrane is more than a millimetre.
4 The amount of \(\mathrm{CO}_{2}\) that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher compared to that of \(\mathrm{O}_{2}\).
Explanation:
As the solubility of \(\mathrm{CO}_{2}\) is 20-25 times higher than that of \(\mathrm{O}_{2}\), the amount of \(\mathrm{CO}_{2}\) that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher compared to that of \(\mathrm{O}_{2}\).

Gaseous \(\left(\mathrm{O}_{2}\right.\) and \(\left.\mathrm{CO}_{2}\right)\) exchange between alveoli and blood, and blood and tissues takes place by
1 Active transport
2 Facilitated diffusion
3 Simple diffusion
4 All of the above
Explanation:
Gaseous \(\left(\mathrm{O}_{2}\right.\) and \(\left.\mathrm{CO}_{2}\right)\) exchange between alveoil and blood, and tissues takes place by simple diffusion.
