Cilia: Cilia are small hair-like structures on the outside of some single-celled organisms and are used for movement. Cilia also are present on most of the human body cells. Fallopian tubes and the trachea in women have a special type of cilia that help transport substances along the tissues' surfaces.

Villi: 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. Hence from the blood stream, the absorbed food is delivered to each and every cell of the body.
