hey

The small intestine has millions of tiny finger-like projections called villi. These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels which absorb the digested food and carry it to the blood stream

Air

Cartilage and smooth muscle provide structure, protection, and function for the air passages. The inner surface of each bronchus is lined with mucous glands and small cilia, hair-like structures designed to filter dust and other foreign particles from the air as it passes through the bronchi.
