Whose name is attached to the folds in the lining of the small intestine that increase absorption?
Quick Answer
The intestinal villi are tiny finger-like projections that increase the surface area for nutrient absorption.
The Full Story
The villi line the small intestine and massively increase the surface area available for absorbing nutrients. Each villus is covered with cells that can take up sugars, amino acids, and other digested substances. Inside each villus are capillaries and lacteals that transport nutrients into the blood and lymph. This structure is one of the key reasons the small intestine is so efficient.
