Acinus

An acinus (adjective: acinar, plural acini) refers to any cluster of cells that resembles a many-lobed "berry," such as a raspberry (acinus is Latin for berry). The berry-shaped termination of an exocrine gland, where the secretion is produced is acinar in form, as is the alveolar sac containing multiple alveoli in the lungs.

Exocrine glands

Acinar exocrine glands are found in many organs, including: the stomach
the sebaceous gland of the scalp
the salivary glands of the tongue
the liver
the lacrimal glands
the mammary glands
the pancreas
the bulbourethral (Cowper's) glands
Mucous acini usually stain pale, while serous acini usually stain dark.

The term "acinus" is considered synonymous with alveolus by some sources, but not all.

The Lungs

The respiratory bronchioles in the lungs terminate in acini, many-lobed sacs containing groupings of alveoli.
