An organ that synthesizes a substance, such as hormones or breast milk, and releases it, often into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland)
a compressable cylindrical case and its contents around a shaft where it passes through a barrier, intended to prevent the passage of a fluid past the barrier. Examples:
An organ that produces and releases one or more substances for use in the body Some glands produce fluids that affect tissues or organs Others produce hormones or participate in blood production
A group of special cells that make substances so that other parts of the body can work For example, the pancreas is a gland that releases insulin so that other body cells can use glucose (sugar) for energy See also: Endocrine glands
any of various organs that synthesize substances needed by the body and release it through ducts or directly into the bloodstream

A gland is an organ in the body which produces chemical substances for the body to use or get rid of. the hormones secreted by our endocrine glands. sweat glands. A device, such as the outer sleeve of a stuffing box, designed to prevent a fluid from leaking past a moving machine part. an organ of the body which produces a substance that the body needs, such as hormones, sweat, or saliva (glande, from glans ). Collection of cells or tissue that removes specific substances from the blood, alters or concentrates them, and then either releases them for further use by the body or eliminates them. Typically, the functional cells of a gland rest on a membrane and are surrounded by a meshwork of blood vessels. Endocrine, or ductless, glands (e.g., pituitary, thyroid, adrenal) discharge hormones into the bloodstream directly rather than through ducts (see endocrine system). Exocrine glands (e.g., digestive, mammary, salivary, sweat) discharge their products through ducts. adrenal gland suprarenal gland mammary gland parathyroid gland pineal gland pituitary gland prostate gland salivary gland sebaceous gland sweat gland tear duct and gland lachrymal duct and gland thyroid gland
A special organ of plants, usually minute and globular, which often secretes some kind of resinous, gummy, or aromatic product
