AThey equalise air pressure between alveoli
BThey drain surfactant into the bronchioles
CThey let macrophages leave the alveolar wall
DThey carry blood between adjacent capillaries
Answer & Solution
Correct answer: A. They equalise air pressure between alveoli
1. Alveoli are connected to their neighbours by alveolar pores.
2. These pores help maintain equal air pressure throughout the alveoli and the lung.
3. So the first option is correct.
4. Blood does not pass through alveolar pores, since blood stays inside the pulmonary capillary network, ruling out the fourth option.
