bile canaliculi

Bile canaliculus (plural:bile canaliculi; also called bile capillaries) is a thin tube that collects bile secreted by hepatocytes. The bile canaliculi merge and form bile ductules, which eventually become common hepatic duct.Hepatocytes are  polyhedral in shape, therefore having no set shape or design. They have surfaces facing the sinusoids, (called sinusoidal faces) and surfaces which contact other hepatocytes, (called lateral faces). Bile Canaliculi are formed by grooves on some of the lateral faces of these hepatocytes.
