The digestive system of a frog includes all the main organs that help it eat, digest, and absorb food. The main parts are the mouth, buccal cavity, pharynx, oesophagus, stomach, intestine, cloaca, and liver with gall bladder.

Main Key Labelling Points

• Mouth - starts digestion.
• Oesophagus - passes food to the stomach.
• Stomach - digests food with acids and enzymes.
• Small intestine - absorbs nutrients.
• Large intestine - absorbs water and sends waste to cloaca.
• Liver & pancreas - help with bile and enzyme secretion.

Tip: In the diagram, always label the liver, stomach, small intestine, and cloaca clearly - these fetch marks in exams.
