Final answer:

Step-by-step explanation:
The secretion of hormones by the pituitary gland is an example of endocrine signaling. Endocrine signaling involves the release of hormones into the bloodstream, which then travel to target cells or tissues to elicit a response. In this case, the pituitary gland secretes hormones that regulate various functions in the body, such as growth, reproduction, and metabolism.
