  • 10. The Avian Stomach
    • 2 . The "gizzard" which is located after the proventriculus, it is very muscular and is used for grinding food.

  • 11. The Small Intestine
    • The small intestine varies in length depending on the diet. It is longer in herbivores (plant eating birds) and shorter in carnivores (flesh eating birds).

  • 12. The Small Intestine
    • The functions of the small intestine are similar to the small intestine of ruminants and monogastrics

  • 13. The Large Intestine
    • The functions of the large intestine are similar to the small intestine of ruminants and monogastrics.

  • 16. The Large Intestine
    • The "cloaca" which, is located at the terminal end of the large intestine is a chamber into which the urinary and genital canals open.

  • 17. The Large Intestine
    • At the junction of the small and large intestine is where the two "ceca" pouches are located.

  • 18. The Large Intestine
    • The two ceca pouches further contribute to aiding in fiber digestion and absorption.
