A gland is an organ or group of cells that secretes (produces) various substances used in keeping the body functioning. Lymph nodes are often referred to as glands, particularly in the neck, but this is incorrect terminology.

Glands are either exocrine (they pour their secretions outside the blood stream) or endocrine (they pour their secretions into the blood stream).
