1. Stomach: First site ofchemical digestion,breaks down food2. Liver: Makes bile(aids in digestion)3. Gall bladder: Storesbile4. Esophagus: Tube thatleads to the stomach5. Pancreas:Makesinsulin (aids indigestion)6.Small Intestine(duodenum and ileum):absorb nutrients fromfood7. Mesentery: Holdscoils of the smallintestine together8. Large Intestine:Collects waste, absorbswater9. Spleen:Part of circulatory system, stores blood10. Cloaca: Where sperm, eggs, urine, and feces exit.11. Artery;take blood away from the heart12. Vein:take blood toward the heart13. left atriumpumps blood into the ventricle14. Right atriumpumps blood into the ventricle15. Lung:organ for oxygen and carbon dioxide exchange1. Locate and label the largest organ in the abdominal cavity it is the reddish brownLIVER.How many lobes does the liver have?32. Locate the greenish sac attached to the liver. This is theGALL BLADDER.What is storedin the gall bladder? What does bile digest?Bile, helps digest food!
3.Beneath and to the right of the liver is a j shapedSTOMACH. With your scissors open the Jof the stomach to observe what the frog may have eaten.Was there anything in the stomach?What do you think the frog ate?4. The stomach attaches to the small intestine. The straight part of the small intestine is calledtheDUODENUMand the coiled section is theILEUM. The coils of the ileum are connected bythin transparent membranes with blood vessels. This tissue is called theMESENTERY.Mesentery helps keep your intestine from knotting up.After cutting the small intestine awayfrom the large intestine, measure how long your small intestine is in cm and inches.____________________cm. _______________________ inches.Name the two sections of the small intestine:1.Duodenum2.Ileum5. The small intestine widens to form theLARGE INTESTINE. The large intestine is a straighttube leading to the anus. The lower portion of the large intestine is called thecloaca. Waste,urine and sex cells are expelled here.6. In the mesentery along the inner curve of the stomach locate the pinkishPANCREAS. In themesentery find a reddish spherical structure call the spleen. Thespleenfilters out worn out redblood cells and platelets from the blood.7. The respiratory system consists of the nostrils, trachea and bronchi which opens into twolungs. Locate theLUNGS, 2 reddish brown saclike structures.8. The circulatory system consists of the heart, blood vessels, and blood. The heart has tworeceiving chambers, orATRIA(singular: atrium),and one sending chamber, orventricle.Blood is carried to the heart in vessels called veins. Veins from different parts of the body enterthe right and left atria. Blood from both atria goes into the ventricle and then is pumped into thearteries,which are blood vessels that carry blood away from the heart. The heart is locatedbetween the lungs. Compare the thickness of the atria and the ventricle.Why is the ventricle so much thicker than the atria?
