Answer:

The alveoli fill up with air each time you breathe in, making the lungs expand. The blood in the mesh-like network of tiny capillaries that surrounds each alveolus absorbs oxygen in the air within the alveoli. ... From these discussions we can conclude that alveoli is the structural and functional unit of the lung.
