digestive system
-The liver is composed of three lobes. The lobes are known as: right, left anterior, and left posterior.
-Between the right and left lobe there is the bile storing gall bladder, greenish in color. The third liver lobe is small and lies dorsal to the gall bladder.
-Lift the liver lobe to see the stomach, which is white and J-shaped.
-Anteriorly the stomach connects to the esophagus.
-Posteriorly, it connects with the small intestine.
-In the small intestine, the first portion is the duodenum.
-In the section that runs parallel to the stomach is the pancreas, and an important digestive gland that secretes pancreatic juice into the duodenum. This portion of the small intestine also receives bile from the liver and gall bladder.
-The bile duct from the gall bladder passes through the pancreas. The duodenum receives both bile and pancreatic juice through the same duct.
-Where the duodenum ends and the ileum begins.
-Along the coiled section of the ileum, there are mesenteries, membranes that holds the coils together. The double membrane carries blood vessels and nerves.
-Held by mesenteries within the folds of the small intestine, is the spleen. (It is not actually part of the digestive system, it is part of the circulatory system.)
-Following the ileum is the large intestine (colon).
-The back portion of this part of the colon is covered by the urinary bladder, a thin-walled sac that holds urine.
-The large intestine opens into the cloaca. (*Fun fact: cloaca means sewer*) Solid and urinary wastes exit the cloaca.
-The cloaca opens to the outside of the frog via the anus.
