Acinus

An acinus (/ˈæsɪnəs/; plural, acini; adjective, acinar /ˈæsɪnər/ or acinous) 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.
