The tiny projections on the wall of the small intestine which absorb food coming from the duodenum are called villi. Villi are finger-like projections that line the small intestine and help to increase the surface area for absorption of nutrients. They are lined with microvilli, which are even smaller projections that further increase the surface area for absorption.
