Digestive System
How The Northern Leopard Frog Digests food
1.The frog uses its sticky, cleft tongue to catch flies and other small moving prey.[1]
2.The eyes assist in the swallowing of food as they can be retracted through holes in the skull and help push food down the throat.
3.The food goes through the oesophagus.
4. Into the stomach where digestive enzymes are added and it is churned up.
5. It then proceeds to the small intestine (duodenum and ileum) where most digestion occurs.
6. Pancreatic juice, and bile, are secreted into the small intestine, where the fluids digest the food and the nutrients are absorbed.
7.The food residue passes into the large intestine where excess water is removed and the wastes are passed out through the cloaca.[1]
