Acinus | Lungs - The Common Vein
The system that starts at the respiratory bronchiole and terminates at the alveoli is called an acinus, and it is functionally characterized by having the ability to both conduct air as well as enable gas exchange. The acinus averages about 7mm (4-8mm)in diameter.
Acinus - an overview | ScienceDirect Topics
The acinus is a functional unit mainly dedicated to the production and secretion of digestive enzymes (6 as much as 20 g daily). It is composed of 15 to 100 pyramidal-shaped cells (as much as 30 µm apical base height) known as acinar cells (Cleveland et al, 2012).
