Atrabiliary capsules refer to small, sac-like structures found in the liver, specifically within the hepatic lobules. These capsules are responsible for storing bile, a yellowish-green fluid produced by the liver and released into the small intestine to aid in the digestion and absorption of fats.
The term "atrabiliary" is derived from the Latin word "aatrix," meaning black bile, and "bile," referring to the fluid produced by the liver. These capsules are named so due to their association with the secretion and storage of bile, an essential component for proper digestion.
The atrabiliary capsules are interconnected and located adjacent to the hepatic cells, known as hepatocytes, which produce bile. These small sacs act as reservoirs for bile and assist in its transportation throughout the liver.
Furthermore, atrabiliary capsules are lined with specialized cells called cholangiocytes, which aid in bile storage and facilitate its release into the bile ducts when needed for digestion. The release of stored bile occurs in response to hormonal signals and activation of certain neural pathways.
Overall, atrabiliary capsules play a crucial role in the processing and storage of bile, thus contributing to the overall digestive function and maintenance of homeostasis within the human body.
