The figure given below shows a small part of human lung where exchange of gas takes place. In which one of the options given below, the one part A, B, C or D is correctly identified along with its function.
a)
A – Alveolar cavity - main site of exchange of respiratory gases
b)
D – Capillary wall - exchange of gases takes place here
c)
B - Red blood cell - transport of mainly haemoglobin
d)
C - Arterial capillary – passes oxygen to tissues

Alveoli are the primary sites of exchange of gases. The exchange of gases (
and C
) between the alveoli and the blood capillary occurs by simple diffusion.
