acinus
Quick Summary
An acinus is a small sac-like structure that terminates the ducts of certain exocrine glands and is lined with secretory cells. The term "acinar" is an adjective meaning relating to or comprising an acinus.12
In the human body, acinar cells are found in the pancreas, where they produce digestive enzymes. These enzymes, including proteases, lipases, and amylases, are crucial for breaking down proteins, fats, and carbohydrates in the small intestine.3
In the lungs, the acinus is a cluster of alveoli (air sacs) that resembles a bunch of grapes. This is the primary site for gas exchange in the lungs. Diseases affecting the lungs, such as pneumonia and emphysema, can involve the acinar structures.4
