Which structures and organs of the frog digestive system develop as tubes or chambers within its tubular digestive tract?
Digestive Organs The esophagus is the tube that allows food to travel from the mouth to the curved, white stomach sac. Food then continues to the coiled tubes called the small intestine where most digestion and nutrient absorption occurs. Digestive juices such as bile are made by the liver and pancreas.
