• absorb water.

• produce bile.

• store roughage.

The main function of the esophagus is to:

• break down roughage into amino acids.

• chew feed into smaller particles.

• connect the mouth to the stomach

• produce bile.

Most food nutrients used by nonruminants such as swine are absorbed from the:

• large intestine.

• rumen.

• small intestine.

• stomach.

The part of the poultry digestive system where both feces and urine pass out of the body is the:

• crop.

• gizzard.

• small intestine.

• vent.

The main function of the liver is to:

• absorb water.
