Concept:The pancreas is the organ that performs both exocrine and endocrine functions.
Explanation:An exocrine gland releases substances through ducts, while an endocrine gland releases hormones directly into the blood.
The pancreas produces digestive enzymes, such as trypsin and amylase, as an exocrine function.
It also produces hormones, including insulin and glucagon, as an endocrine function.
The ileum mainly digests and absorbs food.
The gall bladder stores bile and does not produce hormones.
The kidney produces urine and some hormones, but not digestive enzymes.
Therefore, only the pancreas produces both hormones and enzymes.
