Chicken liver, that is, chicken gizzard, or the stomach of chicken, is also called dried chicken mushroom and chicken gizzard. Unlike other animals, the stomach of birds is divided into glandular stomach and muscular stomach.

Therefore, the chicken gizzard is the stomach that helps the chicken digest food.
