Gland

Gland, an organ in an animal's body that synthesises a substance for release, often into the bloodstream (endocrine gland) or into cavity inside the body or outer surface (exocrine gland).

Humans have a large variety of glands, from the pituitary gland in the brain, to sweat glands over the body's skin that release perspiration to regulate the body's temperature.
