The part of the alimentary system of a bird where food is ground into small particles is the?

A.

cloaca

B.

stomach

C.

crop

D.

gizzard

Correct answer is D

The gizzard is the mechanical stomach of a bird. It is located just after the true or glandular stomach in the gastrointestinal system. Since poultry have no teeth and swallow food whole, this muscular organ, sometimes called hen's teeth, mechanically grinds and mixes the bird's feed.
