  2. Tympanum Lungs External Nares Liver Internal Nares Gall Bladder Maxillary Teeth Stomach Vomerine Teeth Small Intestine Eustachian Tubes Large Intestine Tongue Spleen Esophagus Kidney Glottis Oviducts/Eggs Heart Testis

  3. Tympanum The tympanum, found just behind the eyes, functions as the ears of the frog. They receive sound waves both above and below water allowing the frog to hear. Home

  4. External Nares The nares primary role is to let air into and out of the frog. This is a view of the nares from outside of the frog. Home

  5. Internal Nares The nares primary role is to let air into and out of the frog. This is a view of the nares from inside of the frog. Home

  6. Maxillary Teeth This set of teeth is used for holding prey. Home

  7. This set of teeth is also used for holding prey. Vomerine Teeth Home

  8. The eustachian tubes function to equalize pressure on both sides of the eardrum or tympanum Eustachian Tubes Home

  9. Tongue The tongue aids in swallowing and catching prey. In humans the tongue also aids in speech and taste. Home

  10. Glottis The glottis is the opening between the vocal chords at the upper part of the windpipe or larynx. Home

  11. Esophagus Food is swallowed through the esophagus where peristalsis aids its movement to the stomach. Home

  12. Lungs The lungs transport oxygen to the blood as well as remove waste like carbon dioxide through a process called respiration. Home

  13. Heart Unlike the human heart the heart of a frog only has three chambers (two atria and one ventricle) however the role and function is the same. The heart pumps blood throughout the body carrying oxygen and nutrients and picking up waste to be filtered by other parts of the body. Home

  14. Large Intestine The main role of the large intestine is to absorb water and store fecal material until it can be excreted from the body. Home

  15. Small Intestine The small intestine receives the mixture of chyme from the stomach through the pyloric valve. In the small intestine nutrients are absorbed from the tiny villi lining the inner walls of the small intestine. Home

  16. Stomach In the stomach food is further broken down by gastric juices and peristalsis until it becomes a liquid substance called chyme. Home

  17. Liver The liver produces bile, a substance that emulsifies fats contained within the food we eat, and stores it in the gall bladder to be secreted into the small intestine. Home

  18. Gall Bladder The gall bladder stores bile that is received from the liver. Bile is secreted from the gall bladder into the first section of the small intestine (duodenum) to help aid in digestion. Home

  19. Spleen The spleen helps to destroy old red blood cells and lymphocytes, which are cells that produce antibodies to help fight infected and cancerous cells. Home

  20. Kidneys The Kidneys filter out waste from the blood through structures known as nephrons. The waste removed is combined with water to form urine. Home

  21. Oviducts & Eggs The oviducts are tubes that carry eggs from the ovaries to the uterus. The eggs are the female reproductive cell. Home

  22. Testis The testis are the male reproductive gland that produce sperm and male hormones such as testosterone. Home
