Verified step by step guidance1
Begin by understanding the difference between endocrine and exocrine glands. Endocrine glands release hormones directly into the bloodstream, while exocrine glands release substances through ducts to the outside of the body or into a body cavity.
Identify the primary function of each gland listed in the options: Pancreas, Adrenal gland, Pituitary gland, and Thyroid gland.
Examine the pancreas: It has both endocrine functions (releasing insulin and glucagon into the bloodstream) and exocrine functions (producing digestive enzymes that are released into the small intestine via ducts).
Consider the adrenal gland, pituitary gland, and thyroid gland: These glands primarily function as endocrine glands, releasing hormones directly into the bloodstream without any exocrine activity.
Conclude that the pancreas is unique among the options because it performs both endocrine and exocrine functions, making it the correct answer.
