The secretions of the pancreas enter the duodenum by way of the pancreatic duct. frogs- the pancreas is located behind the stomach and intestines. It has the appearance of a narrow yellow ribbon and is located near the mesentery, which is a transparent strip of tissue that holds the intestines together. Pig Pancreas: a bumpy organ located along the underside of the stomach, a pancreatic duct leads to the duodenum. The pancreas makes insulin, which is necessary for the proper uptake of sugars from the blood. 2. The shark kidney and its ducts are quite different from those in higher vertebrates. The relationship between the urinary and genital structures is also quite different. The kidneys are flattened, ribbon-like, darkly colored structures Iying dorsally on either side of the midline, along the entire length of the body cavity. A tough white glistening strip of connective tissue is found between the kidneys in the midline. salt and water balance, eliminating toxic wastes The kidneys of freshwater fish produce very dilute urine, as their challenge is to hang on to salt and get rid of excessive water. The kidneys of saltwater fish have the opposite challenge: hanging on to water, while getting rid of salt. pig-The urinary system functions to remove toxins from a pig\'s blood and maintain the fluid levels in the body. Urine exits the bladder through the urethra of the pig the function of kidneys of shark fish and pig are different due to their position, sturctutre and environment to adapt. shark- elongated gonads located on either side of the stomach. Frog-The gonads are mesoder¬mal in origin and develop from a pair of genital ridges of the embryo. The genital ridges are the folds of coelomic epithelium lying on the medial sides of the embryonic kidneys. When fully formed, the gonads hang from the dorsal body wall of the double folds of peritoneum called as \'Mesorchia\' in the case of testes and \'mesovaria\' in the case of ovaries. Fish- gonads are paired organs of similar size, which can be partially or totally fused. There may also be a range of secondary organs that increase reproductive fitness. The genital papilla is a small, fleshy tube behind the output in some fishes, from which the sperm or eggs are released; the sex of a fish often can be determined by the shape of its papilla.
