Gland
A gland was a group of s, or an organ that produced a chemical secretion. 

The study of glands was known as endocrinology.

In 2372, Doctor Julian Bashir was at a loss to explain where Goran'Agar's internal supply of ketracel-white was coming from, as no glands appeared to be producing it. ()
