Vomarine and Maxillary Teeth: Used for holding prey Internal Nares (nostrils) breathing Eustachian Tubes: equalize pressure in inner ear Glottis : Tube leading to the lungs Esophagus: Tube leading to the stomach Tongue: Front attached, aids in grabbing prey Tympanic Membrane: eardrum, located behind eyes Nictitating Membrane: clear eyelid, protects the eye

Peritoneum: Spiderweb like membrane that covers organs

Stomach: First site of chemical digestion, breaks down food

Liver: Makes bile (aids in digestion)

Gall bladder: Stores bile

Esophagus: Tube that leads to the stomach

Pancreas: Makes insulin (aids in digestion)

Small Intestine (duodenum and ileum): absorb nutrients from food
Mesentery: Holds coils of the small intestine together

Large Intestine: Collects waste, absorbs water

Cloaca: "Sewer": eggs, sperm, urine and feces enter this area

Spleen: Part of circulatory system, stores blood

Urogenital System

Kidneys: Filter Blood

Ureters: Carry urine from kidneys to bladder

Testes: Make sperm

Oviducts: eggs travel through these

Ovary: makes egg (usually not visible on frog)

Urinary Bladder: Stores Urine

Cloaca: Where sperm, eggs, urine, and feces exit. The "Sewer"
