In the digestive system of Rana tigrina, what are the specific origins, storage sites, and entering ducts of bile and pancreatic secretions?

1. Bile is secreted by the stomach lining, stored in the liver lobes, and released into the ileum via the ureter.
2. Bile is produced by the gall bladder, concentrated in the pancreas, and poured independently into the stomach.
3. Bile and pancreatic juice are both produced in the spleen and delivered directly to the rectum.
4. Bile is secreted by the liver, stored in the gall bladder, and delivered with pancreatic juice to the duodenum via a common bile duct.
