Absorption

Absorption - The process by which fluids or other substances are taken up by body tissues. The term is commonly applied to the uptake of the nutrients from food into blood and lymph from the digestive tract.

The major site of absorption is the small intestine, which is lined with microscopic finger-like projections called villi (see villus). The villi greatly increase the surface area of the intestine, thereby increasing the rate of absorption.
