2) any of various animal structures (as a lymph node) suggestive of glands though not secretory in function
gland·less 'glan-dləs adj

* * *

n.
an organ or group of cells that is specialized for synthesizing and secreting certain fluids, either for use in the body or for excretion. There are two main groups of glands: the exocrine gland, which discharge their secretions by means of ducts, and the endocrine gland, which secrete their products - hormones - directly into the bloodstream. See also secretion.
