used by the organism for food.

3. Absorption
•Absorption is the taking of the digested

4. MONOGASTRIC DIGESTIVE SYSTEM
•A monogastric digestive system has one
simple stomach.

5. AVIAN DIGESTIVE SYSTEM
•The avian digestive system is found in
poultry.

type. Since poultry do not have teeth, there
is no chewing.

7. The crop
•The crop is where the food is stored and

•Food then moves from the crop to the
proventriculus.

8. The proventriculus
•The proventriculus is the stomach in a bird,
where gastric enzymes and hydrochloric acid
are secreted.

9. The gizzard
•From the proventriculus, the food makes its
way to the gizzard.
• The gizzard is a very muscular organ, which
normally contains grit or stones that function
like teeth to grind the food.

10. Secretin
• It is in the duodenum and signals the secretion of
sodium bicarbonate in the pancreas and it
stimulates the bile secretion in the liver.

11. Gastrin
• It is in the stomach and stimulates the gastric
glands to secrete pepsinogen (an inactive form
of the enzyme pepsin) and hydrochloric acid.

12. Cholecystokinin
• (CCK) - is in the duodenum and stimulates the
release of digestive enzymes in the pancreas and
stimulates the emptying of bile in the gall bladder.

13. Bolus
•Food in mouth is called bolus.

14. Chyme
Food in stomach is called chyme

15. Bloat
•A distention of the rumen or the large colon by
gases or fermentation.

16. Gastritis
•Inflammation of stomach

17. Enteritis
•Inflammation of intestine.

18. Rumination
•The process of regurgitating previously
eaten feed, reswallowing the liquids, and
