Multiple Choice

Why is the pancreas considered both an endocrine and an exocrine gland?

Because it secretes insulin directly into the bloodstream and digestive enzymes into the small intestine.

Because it only produces digestive enzymes for the small intestine.

Verified step by step guidance

Understand the definition of endocrine and exocrine glands: Endocrine glands release hormones directly into the bloodstream, while exocrine glands secrete substances through ducts to an epithelial surface or into body cavities.

Identify the endocrine function of the pancreas: The pancreas secretes hormones such as insulin and glucagon directly into the bloodstream to regulate blood sugar levels.

Identify the exocrine function of the pancreas: The pancreas produces digestive enzymes, such as amylase, lipase, and proteases, which are secreted into the small intestine via the pancreatic duct to aid in digestion.

Compare the functions: Recognize that the pancreas performs both endocrine and exocrine functions, making it unique among glands.

Conclude why the pancreas is considered both an endocrine and an exocrine gland: It fulfills the criteria for both types of glands by secreting hormones into the bloodstream and digestive enzymes into the small intestine.
