Question

Which statement regarding the structures of the endocrine system requires clarification?

Answers

  1. “The thyroid is an endocrine gland.”
    • Rationale:

      The thyroid secretes and stores hormones; therefore, this statement does not require clarification.

  2. “The pancreas is an endocrine gland.”

Overview

The endocrine system is the collection of glands. These glands produce hormones that regulate many functions within the body.

Explanation

Learning Outcomes

Specific functions that are regulated by endocrine glands include, but are not limited to, growth and development, metabolism, mood, reproduction, sexual function, sleep, and tissue function. There are nine glands within the endocrine system. The thymus, while previously classified as an endocrine gland, is no longer included as this structure does not produce hormones.

Test Taking Tip

Consider the structure that does not release hormones to answer this question correctly.
