Bile Canaliculus

Bile canaliculus (pronounced: /ˈbaɪl kəˌnælɪkjuːləs/) is a term used in the field of Anatomy and Hepatology. The term originates from the Latin words "bilis" meaning "bile" and "canaliculus" meaning "small channel".

Definition

A bile canaliculus is a small duct within the liver that transports bile from hepatocytes (liver cells) to the bile ducts. It is part of the biliary tree, a system of vessels that carry bile, a fluid produced by the liver to aid in digestion.

Function

The primary function of the bile canaliculus is to transport bile from the hepatocytes where it is produced, to the bile ducts. This process is essential for the digestion and absorption of dietary fats.

Structure

The bile canaliculi are tiny channels, typically less than 1 micrometer in diameter, that form a network throughout the liver. They are lined by the canalicular membrane of the hepatocytes, which is rich in proteins necessary for bile formation and transport.
