Gland

A gland is a specialized organ or group of cells that secretes substances within the body or onto its surface. These substances, called secretions, play crucial roles in various physiological processes, including digestion, hormone regulation, lubrication, and waste elimination. Glands can be categorized based on their secretion type, such as endocrine glands, which release hormones directly into the bloodstream, or exocrine glands, which release substances through ducts. The structure and function of glands vary depending on their specific role within the body.
