How Does the Gizzard Function in a Chicken's Digestive System?

Discover the role of the gizzard in chicken digestion and how it aids in food processing.

9 views

The gizzard is a specialized stomach found in chickens and other birds. It contains small stones or grit that the bird has ingested. These stones grind up food, aiding in the mechanical breakdown of tough, fibrous material. The gizzard effectively acts as the bird's teeth, ensuring food is well-processed before moving to the intestines for nutrient absorption. This adaptation is essential for the bird's digestion, especially given its lack of teeth.
