A gland is a functional unit of cells that works together to create and release a product into a duct or directly to the bloodstream. Two principal types of glands exist: exocrine and endocrine. The key difference between the two types is that, whereas exocrine glands secrete substances into a ductal system to an epithelial surface, endocrine glands secrete products directly into the bloodstream .
