Frog-Digestive system

Digestive system

            The frog is a carnivorous animal. It feeds chiefly on living insects, spiders and worms. These are captured with the help of tongue and swallowed.

          The digestive system of frog consists of the alimentary canal and its associated glands.

           The alimentary canal starts in the mouth. The upper jaw has a row of maxillary teeth. There are no teeth in lower jaw. A bifid tongue is present in the lower jaw to capture the prey. Mouth leads into buccal cavity which in turn leads into oesophagus and muscular elongated stomach.

            The stomach  leads into duodenum which is the first part of the small intestine. The duodenum leads into ileum which is the next region of the small intestine. The ileum open into the rectum which opens into the cloaca.

            The two important associated digestive glands are the liver and the pancreas.
