Question
Explain digestion in frogs.
✓
Answer
Digestion in Frog:
In the stomach digestion of food takes place by the action of HCl and gastric juices secreted from the walls of the stomach.
Partially digested food called chyme is passed from stomach to the first part of the intestine, the duodenum. The duodenum receives bile from gall bladder and pancreatic juices from the pancreas through a common bile duct.
Bile emulsifies fat and pancreatic juices digest carbohydrates and proteins. Final digestion takes place in the intestine.
Digested food is absorbed by the numerous finger-like folds in the inner wall of intestine called villi and microvilli.
