Answer:
Pancreas.
Explanation:
Pancreas is an organ that acts as both exocrine as well as endocrine gland. As exocrine gland, it secretes digestive enzymes into the small intestine that help in digestion of complex food molecules.

Thus, the correct answer is 'pancreas.'

the igneous rocks: they are generally volcanic type rocks.
Sedimentary rocks: rocks that are formed for the accumulation of sediments.
the metamorphic rocks: they are rocks characterized by the modification of others already existing in the interior of the earth by a process called metamorphism
