  1. The Avian Digestive System By Gemma Dalena

  2. Overview of Information Presented: • The Avian Digestive System • Parts of the Avian Digestive System • Esophagus • Stomach • Small Intestine • Large Intestine http://www.calaged.org/ResourceFiles/Curriculum/advcluster/3000.htm Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  3. Information Guide All Information Provided by this PowerPoint Presentation can be found on the at: http://www.calaged.org/ResourceFiles/Curriculum/advcluster/3000.htm • Under the California Agriculture Core Curriculum Animal Science • Animal Physiology –(CLF3201) The Digestive Process Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  4. The Avian Digestive System • This digestive system is adapted for grinding hard or encased (shells of seeds) food. Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  5. Parts of the Avian Digestive System • The Mouth • Saliva is secreted to moisten food and aid in swallowing since avian species do not have teeth. Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  6. The Esophagus • The Esophagus connects the mouth to the stomach. Esophagus Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  7. The Esophagus • has a modification which is called the "crop" where food is stored and further moistened Crop Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  8. The Avian Stomach Consists of Two Parts: Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  9. The Avian Stomach Consists of two parts. 1.The "proventriculus" which provides digestive secretions. Proventriculus Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  10. The Avian Stomach 2. The "gizzard" which is located after the proventriculus, it is very muscular and is used for grinding food. Gizzard Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  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). Part of the small intestine Parts of the small intestine Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  12. The Small Intestine • The functions of the small intestine are similar to the small intestine of ruminants and monogastrics Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  13. The Large Intestine • The functions of the large intestine are similar to the small intestine of ruminants and monogastrics. Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  14. The Large Intestine Ruminants Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  15. The Large Intestine Monogastrics Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  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. Large Intestine cloaca Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  17. The Large Intestine • At the junction of the small and large intestine is where the two "ceca" pouches are located. Compilation: AECD, California || For more e-learning resources visit www.kashvet.org

  18. The Large Intestine • The two ceca pouches further contribute to aiding in fiber digestion and absorption. CecaPouch Ceca Pouch Compilation: AECD, California || For more e-learning resources visit www.kashvet.org
