Acinar cells are specialized cells found in the pancreas that play a crucial role in digestion. They are responsible for producing and secreting digestive enzymes, such as amylase, lipase, and proteases, which help break down carbohydrates, fats, and proteins in the food we eat. These enzymes are released into the small intestine, where they aid in the digestion process. In addition to their digestive functions, acinar cells also produce a fluid rich in bicarbonate, which helps neutralize stomach acid as it enters the small intestine. This protective mechanism ensures that the enzymes can function optimally in the more alkaline environment of the intestine, promoting effective digestion and nutrient absorption.
