Taste Opening to the gullet grasping hearing Digestive System *Esophagus *Stomach *Small Intestine *Large Intestine Cloaca *Gallbladder *Pancreas *Spleen Connects the opeining of the mouth to the stomach Protein digestion Digests lipids, carbohydrates and proteins. Reabsorbs water from the undigested material. Common passage for feces and urine. Also a passage for sperm or eggs. Releases enzymes into the small intestine which are used to digest fats. Release enzymes into the small intestine which are involved in the digestion of fats and proteins. Filters the blood by destroying ageing red blood cells.

Osmosis is involved in this process. stores fat which can be used for energy. Carries urine from the kdney to the bladder stores urine. produces sperm cells produces egg cells duct from which egss are released. 2 Respiratory System *Lungs Removes carbon dioxide from the blood and replaces it with oxygen.
