Cholestasis - Normal Bile Formation

Normal Bile Formation

Bile formation is a secretory function of the liver. It begins in bile canaliculi that form between two adjacent surfaces of liver cells (hepatocytes) similar to the terminal branches of a tree. The canaliculi join each other to form larger and larger structures, sometimes referred to as Canals of Hering, which themselves join to form small bile ductules that have an epithelial surface. The ductules join to form bile ducts that eventually form either the right main hepatic duct that drains the right lobe of the liver, or the left main hepatic duct draining the left lobe of the liver. The two ducts join to form the common hepatic duct, which in turn joins the cystic duct from the gall bladder, to give the common bile duct. This duct then enters the duodenum at the ampulla of Vater.

Famous quotes containing the words formation, normal and/or bile:

    The moral virtues, then, are produced in us neither by nature nor against nature. Nature, indeed, prepares in us the ground for their reception, but their complete formation is the product of habit.
    Aristotle (384–322 B.C.)

    As blacks, we need not be afraid that encouraging moral development, a conscience and guilt will prevent social action. Black children without the ability to feel a normal amount of guilt will victimize their parents, relatives and community first. They are unlikely to be involved in social action to improve the black community. Their self-centered personalities will cause them to look out for themselves without concern for others, black or white.
    James P. Comer (20th century)

    Mister Ward, don’t yur blud bile at the thawt that three million and a half of your culled brethren air a clanking their chains in the South?—Sez I, not a bile! Let ‘em clank!
    Artemus Ward (1834–1867)
