Nictitating membrane
Protects and keeps the eye moist
External nares
External nostril openings for air to enter
Tympanic membrane (aka tympanum)
Allows for hearing above and below the water, larger in males than in females
Tongue
Catches insects and is attached in the front of the mouth
Maxillary teeth
Row of teeth along the outside border of the upper jaw used to hold and grip food tightly
Vomerine teeth
Located between the two internal nares and are used to prevent the escape of prey from the mouth
skin
organ that allows oxygen and CO2 to flow freely in and out of the frog's body
Esophagus
The tube connecting the mouth to the stomach
Glottis
Opening to the lungs, prevents food or water from entering the lungs
bile
a chemical/fluid that aids in digestion of fats; it is secreted into the stomach by the liver and can be stored in the gallbladder.
Spleen
A storage area for blood
Stomach
The main location where chemical and mechanical breakdown of food occurs; after the esophagus
Small Intestine
Chemical digestion of food and nutrients are absorbed into the blood stream here
pancreas
produces insulin and other hormones, which mainly regulate the amount of glucose in the blood
cloaca
Urine, feces, sperm, and eggs exit the body through this opening
lungs
Gas exchange in blood cells occurs here (carbon dioxide is exchanged for oxygen)
Gallbladder
Stores bile
liver
Produces bile needed for the digestion of fats; large brownish- red, 3 lobed organ across the chest
Large Intestine
absorbs/removes water and packages fecal material
Fat bodies
Reserve energy storage to use during hibernation and breeding
teste
Produce sperm cells
kidney
Filter blood of impurities/fluid waste from the blood
bladder
Stores urine until it is released from the body
oviducts
Produces egg cells
eggs
Will produce tadpoles if fertilized when they exit the body
vertebrate
means has a backbone
amphibians
means "double life"
