Verified step by step guidance

Understand the functions of the pancreas: The pancreas is a unique organ that performs both endocrine and exocrine functions.

Define endocrine function: Endocrine glands release hormones directly into the bloodstream. In the pancreas, the endocrine function involves the secretion of insulin and glucagon by the islets of Langerhans to regulate blood sugar levels.

Define exocrine function: Exocrine glands release substances through ducts to the outside of the body or into the digestive tract. The pancreas performs exocrine functions by producing digestive enzymes like amylase, lipase, and proteases, which are secreted into the small intestine via the pancreatic duct.

Compare with other organs: The spleen, liver, and gallbladder do not have both endocrine and exocrine functions. The spleen is primarily involved in filtering blood and immune responses, the liver in metabolism and detoxification, and the gallbladder in storing bile.

Conclude why the pancreas is the correct answer: Given its dual role in hormone secretion and enzyme production, the pancreas is the organ with both endocrine and exocrine functions.
