A compound (exocrine) gland
Compound glands are usually divided by blood vessel-carrying connective tissue into lobes and lobules. The ducts of compound glands are branched and drain several secretory lobules or lobes. The secretory endpieces in such glands are composed of a simple cuboidal epithelia. Ducts with a simple cuboidal epithelium accumulate secretory product from a number of endpieces and finally leave the lobule. They merge with other similar ducts and grow to a larger size; the epithelium of the largest (excretory) ducts is frequently of a stratified type.
