What gland produces insulin and digestive juices, located dorsal to the stomach?

The pancreas is the gland responsible for producing insulin and digestive juices. It is located behind (or dorsal to) the stomach in the human body. The pancreas has both endocrine and exocrine functions. The endocrine part of the pancreas releases insulin into the bloodstream, which helps regulate blood sugar levels. The exocrine part produces digestive juices that are released into the small intestine to aid in the digestion of food.

In contrast, the liver primarily processes nutrients from the digestive system and produces bile, while the spleen is involved in filtering blood and managing immune responses. The gallbladder stores bile produced by the liver but does not produce digestive enzymes or insulin. Thus, the pancreas is uniquely positioned as the gland that fulfills both the roles of insulin production and digestive juice secretion, making it the correct answer to the question.
