They also have moveable lips made of flexible skin, their tongue is usually loose and protrusible. They have salivary glands that expel saliva and help the breaking down and moisture of the food.

Mouth

Similar to ours, the lizard's esophagus is a straight, thin tube that passes through the neck dorsal to the trachea and opens into the stomach.

Esophagus

It is a cylindrical tube, the stomach functions are very similar to ours, but the shape is different.

Stomach

The small intestine is a long, narrow tube. Just as ours, the duodenum receives the bile, and the ileum leads into the large intestine.

Small intestine

It is a small, thick-walled tube, which opens into the cloaca by the anus. The colon is absent.

Large intestine

-PHARYNX -LIVER: (left and right lobe) The liver is a large gland placed on the dorsal side of the stomach, behind the heart, occupies a similar function to our liver. -Cloaca -gall blader -pancreas -duodenum
