5. 4. Avoli are microscopic air sacks in the lungs of mammals
4. Avoli are microscopic air sacks in the lungs of mammals. Which statement best describes how their structure allows the lungs to function properly?
They increase the amount of energy transferred from the lungs to the blood.
They increase the flexibility of the lungs as they expand.
