How Do Lizards Excrete Waste? In snakes and lizards, these wastes are eliminated from the cloaca together with wastes from the digestive system. Prior to the evolution of the metanephric kidney, the products of the male gonad, the testis, traveled through the same duct with the nitrogenous wastes from the kidney.

How do reptiles produce urine?
Reptiles and amphibians lack loops. Instead they excrete uric acid in a colloidal form with proteins. Uric acid excretion requires very little water. Urine from the ureters moves from the cloaca into the rectum by a reverse peristalsis.
Do lizards carry disease?

The Lizard will then swallow the bolus down the esophagus. The esophagus will then push food down the digestive tract.
Where do lizards pee?
