gland

[C] Countable

pl: glands

In biological terms, the word evokes a sense of internal regulation and invisible chemical signaling. It is used almost exclusively in medical or scientific contexts to describe the specialized hardware of the endocrine and exocrine systems. In engineering, the term shifts to a functional description of containment. It describes a specific mechanical interface where a moving part meets a stationary wall, focusing on the tension and compression required to maintain a watertight or airtight seal.

Used for individual biological organs (the thyroid gland) or specific mechanical components (a stuffing gland).
