In contrast to tubular glands, in the second main variety of gland, the secretory portion is enlarged and the lumen variously increased in size. These are termed alveolar glands (or saccular glands, or acinar glands, or acinous glands).
Some sources draw a clear distinction between acinar and alveolar glands, based upon the shape of the lumen.
The term "tubulo-alveolar" (or "tubulo-acinar", or "compound tubulo-acinar", or "compound tubulo-alveolar") is used to describe that start out as branched tubular, and branch further to terminate in alveoli. This type of gland is found in the salivary glands, esophagus, and mammary glands.
