Question

Which statement regarding the endocrine function of the islets of the pancreas requires clarification?

Answers

  1. “This structure secretes insulin.”
    • Rationale:

      This statement does not require clarification because the secretion of insulin is an endocrine function of the islets of the pancreas.

  2. “This structure secretes glucagon.”
    • Rationale:

      This statement does not require clarification because the secretion of glucagon is an endocrine function of the islets of the pancreas.

  3. “This structure secretes somatostatin.”
    • Rationale:

      This statement does not require clarification because the secretion of somatostatin is an endocrine function of the islets of the pancreas.

  4. “This structure secretes digestive enzymes.”
    • Rationale:

      While this is a function of the pancreas, this is a digestive function and not an endocrine function of the islets of the pancreas.

Overview

The pancreas is located behind the stomach that plays an essential role in controlling serum blood glucose levels via secretion of its hormones glucagon and insulin by the islets of the pancreas.

Explanation

Learning Outcomes

The pancreas is an essential endocrine gland. In addition, the pancreas also plays an important role in the digestive process. Specifically, the pancreas produces and releases digestive enzymes and juices in addition to pancreatic enzymes that break down foods as they enter the small intestine within the gastrointestinal tract.

Test Taking Tip

Consider the functions of the pancreas that are not specific to the endocrine system to answer this question correctly.
