			Centroacinar cells are specialized cells located in the [[pancreas]], specifically within the [[exocrine pancreas]]. These cells are an integral part of the [[pancreatic ductal system]] and play a crucial role in the secretion of [[bicarbonate]] and other components of the pancreatic juice.

	Centroacinar cells are ~~small, lightly staining cells that are located in~~ the ~~center~~ of the ~~acinus of~~ the ~~pancreas~~. They are characterized by their ~~location~~ and ~~their relatively~~ pale cytoplasm. ~~The centroacinar~~ cells ~~form the beginning of the [[intercalated duct]] system of~~ the pancreas.		Centroacinar cells are found at the junction of the [[pancreatic acini]] and the [[intercalated ducts]]. They are characterized by their small size and pale-staining cytoplasm. These cells are unique to the pancreas and are not found in other exocrine glands.

	The primary function of centroacinar cells is to ~~produce and~~ secrete a bicarbonate-rich fluid ~~that is a component of pancreatic juice. This fluid~~ helps to neutralize the ~~acidity of the~~ chyme ~~(partially digested food) that enters~~ the ~~small intestine~~ from the stomach. ~~The bicarbonate ions from~~ the ~~centroacinar cells mix with the digestive~~ enzymes ~~secreted by the acinar cells to form the pancreatic juice~~.		The primary function of centroacinar cells is to secrete bicarbonate-rich fluid, which helps to neutralize the acidic chyme entering the [[duodenum]] from the [[stomach]]. This secretion is essential for creating an optimal pH environment for the activity of [[pancreatic enzymes]].

	== ~~Clinical significance~~ ==		== Role in Pancreatic Secretion ==

Centroacinar cells, along with the [[ductal cells]], contribute to the production of the aqueous component of pancreatic juice. This process is regulated by the hormone [[secretin]], which stimulates the secretion of bicarbonate in response to acidic chyme in the duodenum.

'''Centroacinar cells''' are a type of cell found in the [[pancreas]]. They are located in the [[acini]] of the pancreas, specifically in the center of the acinus, hence the name "centroacinar". These cells are part of the [[exocrine system]] of the pancreas and play a crucial role in the production and secretion of [[pancreatic juice]], which aids in digestion.

== Structure ==

Centroacinar cells are small, lightly staining cells that are located in the center of the acinus of the pancreas. They are characterized by their location and their relatively pale cytoplasm. The centroacinar cells form the beginning of the [[intercalated duct]] system of the pancreas.

== Function ==

The primary function of centroacinar cells is to produce and secrete a bicarbonate-rich fluid that is a component of pancreatic juice. This fluid helps to neutralize the acidity of the chyme (partially digested food) that enters the small intestine from the stomach. The bicarbonate ions from the centroacinar cells mix with the digestive enzymes secreted by the acinar cells to form the pancreatic juice.

== Clinical significance ==

Abnormalities or damage to the centroacinar cells can lead to pancreatic disorders. For example, in [[chronic pancreatitis]], the centroacinar cells may be damaged, leading to a decrease in the production of bicarbonate-rich fluid, which can result in digestive problems.
