Answer:
1. If the surface dries out, gas exchange will happen at a very reduced rate since fast-moving gaseous oxygen molecules do not efficiently cross the alveoli membrane.
2. Alveoli are uncountable in number in order to increase the exchange of gases in the lungs. They are too small so that number of alveolus can fit in it and increase the exchange of gases
