Detailed explanation-1: -gizzard, in many birds, the hind part of the stomach, especially modified for grinding food. Located between the saclike crop and the intestine, the gizzard has a thick muscular wall and may contain small stones, or gastroliths, that function in the mechanical breakdown of seeds and other foods.

Detailed explanation-2: -The second part of a bird’s stomach (a part we humans don’t have) is the gizzard or muscular stomach. The gizzard is very thick and muscular in some species, such as ducks, gallinaceous birds (those related to chickens such as grouse, quail, and turkeys), emus, and doves.

Detailed explanation-3: -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 feed whole, this muscular organ, sometimes called hen’s teeth, mechanically grinds and mixes the bird’s feed.

Detailed explanation-4: -The gizzard is also referred to as the muscular stomach or ventriculus. It is connected by the isthmus to the proventriculus and to the duodenum.

Detailed explanation-5: -The gizzard is an oval, muscular, and thick-walled structural organs. It bears six chitinous ridges on which teeth like structures are present which help in grinding and churning of the food. It converts the food into a fine semisolid state. The gizzard is modified in different insects depending upon requirements.
