The light from the Proteus penetrated through what seemed to him a vast thickness of tissue and in its muted intensity, the alveolus was a tremendous cavern, with walls that glinted moistly and distantly.
At the end of each bronchiole are tiny sacs called alveoli, each one of them lined with a thin layer of fluid that keeps each alveolus open.
When a fertilized egg is laid by the queen bee in an ordinary alveolus and the larva is fed with standard food, a small, sterile female, a worker bee, is born.
