Together the human lungs contain approximately 300 to 500 million alveoli.
Explanation:
Alveolar number is closely related to total lung volume, with larger lungs having considerably more alveoli.
Alveolar number is estimated by counting their openings at the level of the free septal edges, where they form a 2-D network.
The number of alveoli is a key structural determinant of lung architecture.
