Gizzards are specialized organs found in the digestive systems of some animals, including birds and reptiles, for grinding food. They are absent in humans. In animals with gizzards, this organ helps break down tough food material using mechanical digestion facilitated by ingested stones or grit. This pre-digested food is then passed along to other digestive organs for further processing and nutrient absorption.
