Lining of the epithelial wall has many convolutions to increase absorption.
Feces are expelled outside the body by the contractions of the anal muscles.
The mucosa layer secretes mucus to facilitate the exit of feces.
Presence of Bacteria which break down undigested food remains into simple substances.

It only involves the processes that build up the large molecules in the body.
It only involves the processes that break down the small molecules in the body.
It only involves the processes that break down the large molecules in the body.
It involves all of the processes that break down and build up molecules in the body.
Fat-soluble vitamins (A, D, E, and K) are absorbed along with dietary proteins.
Water moves down its concentration gradient from the chyme into epithelial cells.
In general all minerals that enter the intestine are absorbed, whether you need them or not.
The free fatty acids and monoacylglycerides (glycerol molecules) that enter the epithelial cells are reincorporated into triglycerides.
A lacteal is surrounded by blood capillaries in the mucosal layer of the ileum.
Products of digestion are transferred to the blood and lymph
There are tiny projections from the epithelial cells called micro-villi
There is an outer covering of multi-layers epithelial cells.

Produces products of less energy-rich than their simple precursors.
Used in catabolic processes that generates energy.
Used in anabolic processes that creates biologically important molecules such as phospholipids.
Fatty acids and glycerol are stored in adipose fat in complex forms such as triglycerides.
Can be used to make glucose.

Some are used as a source of energy.
Some are used to synthesize nitrogen containing compounds.
