==================================================

Question: Lungs

Answer: Located underneath and behind the heart and liver. Lungs attach to the trachea via tubes called bronchi. Two spongy organs

==================================================

Question: Gall Bladder

Answer: Located underneath the lobes of the liver, looks like a small green sac. Gall bladder stores bile and then releases it into the duodenum via the bile duct.

==================================================

Question: Stomach

Answer: Curving from underneath the liver. The stomach is the first major site of chemical digestion. Frogs swallow their meals whole. The pyloric sphincter valve regulates the exit of food from the stomach

==================================================

Question: Pancreas

Answer: This glandular organ is located within the curve of the stomach. It secretes insulin which is needed for the proper breakdown of sugar.

==================================================

Question: Small Intestine

Answer: The first straight portion of the small intestine from the stomach is called the duodenum, the curled portion is the ileum. A membrane called the mesentery holds the ileum together. The blood vessels running through the mesentery will carry absorbed nutrients away from the intestine. Absorption of digested nutrients occurs in the small intestine.

==================================================

Question: Large Intestine

Answer: The small intestine widens into the large intestine. The large intestine is also known as the cloaca in the frog. The cloaca is the last stop before wastes, sperm, or urine exit the frog’s body.

==================================================

Question: Spleen

Answer: Located in the folds of the mesentery and is a dark red spherical object that serves as a holding area for blood, where harmful particles can be filtered out for the immune system

==================================================

Question: Urogenital System

==================================================

Question: Kidneys

Answer: Flattened bean shaped organs located at the lower back of the frog, near the spine. The kidneys filter wastes from the blood. Often fat bodies are attached to the kidney

==================================================

Question: Testes

Answer: In male frogs, these organs are located at the tope of the kidneys

==================================================

Question: Oviducts

Answer: A curly-q type structure around the outside of the kidney. Oviducts are where eggs are produced. males may have similar structures but have no actual purpose called vestigial oviducts.

==================================================

Question: Bladder
