villi

Gut absorption bumps

Villi are tiny finger-like projections that line certain body surfaces, especially the small intestine, where they increase surface area for absorption.

Each villus contains blood vessels that absorb nutrients from digested food.

The singular is villus.

Similar structures appear in the placenta and other organs.

The intestinal villi were damaged by the disease.
