Which of the following describes a gland's primary function?

The primary function of a gland is to produce hormones. Glands are specialized organs that secrete substances such as hormones directly into the bloodstream or into other body fluids where they can exert their effects on various target organs or tissues. Hormones are chemical messengers that regulate numerous physiological processes, including metabolism, growth, development, and mood.

This primary role distinguishes glands from other types of tissues in the body; for instance, while some tissues may be involved in transporting nutrients, providing structural support, or facilitating movement, these functions do not pertain directly to glands. Glands organize and control the release of hormones, which play a critical role in maintaining homeostasis and regulating bodily functions.
