Which major organs make up the digestive tract of a frog?

In order to ingest food, frogs use their tongue as an
appendage to capture and bring in to their mouth flies and other prey. They have
vomerine teeth in the roof of the mouth to aid in holding their prey and maxillary teeth
which help chew the food. Once swallowed, it passes through the espophagus and to the
stomach. In the stomach, chemical digestion occurs. The food next passes through the
small intestine, where further hydrolysis occurs. They have a pancreas which secretes
digestive enzymes as well as the liver which produces bile. Bile can emulsify fat and is
stored in the tiny gall bladder until it is needed. The large intestine collects
undigested material and it then eventually reaches the cloaca. This is a common duct for
the removal of undigested matter or feces and can also be used for excretion of urea and
for the exit of sperm and eggs during reproduction.
