Glands. Glands of the body are classified as either exocrine or endocrine types. Exocrine glands are glands that retain ducts to body surfaces. During development, endocrine glands lose their contacts to embryological surfaces(ducts) and become isolated as small blocks of tissues.n exocrine glands, products of these cells collect in the duct of the gland and flow toward the surface to which the duct is in contact. Since endocrine glands lack ducts, the product is released across the cell membrane into interstitial spaces around the cells.
