What is the acinus of the lungs?
The acinus is composed of respiratory bronchioles, alveolar ducts, and alveolar sacs. It is roughly spherical, resembling a bunch of grapes. Each respiratory bronchiole gives rise to several alveolar ducts and alveolar sacs, giving it the characteristic grape bunch appearance.
