The main function of the esophagus is to:

• chew feed into smaller particles.

• connect the mouth to the stomach.

• produce bile.

What part of the nonruminant digestive system receives, churns, and mixes the feed and adds gastric juice to help in the digestive process?

When the digestive system of a mature cow is inspected, the tube-like structure that one sees connecting the mouth to the stomach is the:

• colon.

• esophagus.

• pancreas.

• small intestine.

The part of a ruminant’s stomach that is the true stomach where gastric juice acts on the feed is the:

• abomasum

• omasum.

• reticulum

• rumen.

The part of the ruminant’s digestive system where partially digested feed is mixed with pancreatic juice, bile, and intestinal juice is the:

• cecum.

• omasum

• large intestine.

• small intestine

When the digestive system of a hen is inspected, the muscled, purplish colored organ that one sees is the:
