A gizzard is an organ found in the digestive tract of some animals, such as birds and reptiles. It works by grinding up food, aided by ingested stones or grit. This mechanical digestion helps break down food into smaller particles, making it easier for digestive enzymes to further process and absorb nutrients. It's crucial for species lacking teeth or those with specialized diets.
