Absorption

Summary points:

Bile and pancreatic juices enter the duodenum.

The three main digestive enzymes are amylase, lipase and trypsin.

Most of the nutrient absorption occurs in the small intestine.

The intestine is lined with tiny projections called villi.

Absorption in the wall of the small intestine is either active of passive.
