(N/A) The digestive system of a frog consists of an alimentary canal and digestive glands.
$1$. Alimentary Canal: It is short because frogs are carnivores and hence the length of the intestine is reduced.
$2$. Mouth: The mouth opens into the buccal cavity that leads to the oesophagus through the pharynx.
$3$. Oesophagus: It is a short tube that opens into the stomach.
$4$. Stomach: The stomach continues into the intestine,rectum,and finally opens outside by the cloaca.
$5$. Digestive Glands: These include the liver (which secretes bile) and the pancreas (which produces digestive enzymes). The bile is stored in the gall bladder.
