Explanation:

The digestive system of a frog consists of a complete alimentary canal and associated digestive glands. The major parts are arranged in sequence from the mouth to the cloaca:

• Mouth – wide opening where food is taken in. 
• Buccal cavity – holds the food; tongue helps capture prey. 
• Pharynx – connects buccal cavity to oesophagus. 
• Oesophagus – short tube that leads to the stomach. 
• Stomach – sac-like organ where food is partially digested by gastric juices. 
• Small intestine (duodenum and ileum) – receives bile and pancreatic juices; final digestion and nutrient absorption occur here. 
• Large intestine – absorbs water and forms feces. 
• Cloaca – common chamber where digestive and other wastes exit the body.

Accessory organs include the liver (produces bile stored in the gall bladder) and the pancreas (produces digestive enzymes). :contentReference[oaicite:0]{index=0}
