What is the relationship between bile ducts and hepatic ducts?

What are the functions of bile canaliculi?

Bile canaliculi act as ducts that collect bile secreted from hepatic cells.

Where does the digestive tract start and end in a fetal pig?

The hepatic duct and the cystic duct extend from the gallbladder and merge to form the common bile duct which carries bile to and from the gallbladder.(Bile is collected in tiny ducts that merge to form the bile ducts of the hepatic triads, which, in turn, join to form the hepatic duct, which carries bile from the liver)

What is the path of bile from its secretion to the gallbladder for storage and concentration and then to the duodenum listing the structures in order?

a. hepatocytes b. bile canaliculi c. bile ducts d. left & right hepatic ducts e. common hepatic duct f. cystic duct g. gallbladder h. cystic duct i. common hepatic duct j. hepatopancreatic ampulla k. duodenum

What is the Pathway of bile from gallbladder to duodenum?

Liver -> right and left hepatic ducts -> common hepatic duct -> cystic duct -> gall bladder.

The common bile duct is formed by the connection of what two ducts?

The Cystic duct from the gallbladder and the Common Hepatic duct from the liver

Which duct connects liver small intestine?

The ducts that connect the liver to the small intestine are used to deliver bile. Bile is an acid containing enzymes that can break down fats, and carry away wastes during digestion. it helps clense and clean the intestines while invloved in the breakdowns of the bugger lipids. Hope this helps, sincerely Stefano.

What is the structure that connects the liver the gallbladder and pancreas?

The hepatic ducts leave the liver and combine to form the common hepatic duct. The gall bladder is connected to the cystic duct which combines with the hepatic duct to form the bile duct, this duct leads to the duodenum.

Trace the flow of bile from the liver to the duodenum listing all of the structure that come into contact with the bile on its journey.?

The hepatocytes in the liver produce bile, which then flows through the left and right hepatic ducts to the common hepatic duct. Once the common hepatic duct is filled, the bile flows into the cystic duct and then into the gallbladder where it is stored. The gallbladder allows the bile to flow back into the cystic duct and then the common bile duct which empties into the duodenum.

How does bile leave the hepatocytes?

The bile produced by hepatocytes drains into canaliculi, which are small channels that take the bile to the bile ductules. These eventually merge to become the common bile duct, which opens into the duodenum (the first part of the small intestine).

What do dilated intrahepatic bile ducts indicate?

Dilated intrahepatic bile ducts usually indicate an abnormal blockage downstream. Intrahepatic bile ducts are the small bile ducts in the liver that collect the liver cells' bile for transport to the larger bile ducts that become a single bile duct.

What is a biliary tract?

The biliary tract consists of the liver, gallbladder, and bile ducts.A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. These cells are involved in: *Protein synthesis *Protein storage *Transformation of carbohydrates *Synthesis of cholesterol, bile salts and phospholipids *Detoxification, modification, and excretion of exogenous and endogenous substances *Initiation of formation and secretion Bile canaliculus (plural:bile canaliculi; also called bile capillaries) is a thin tube that collects bile secreted by hepatocytes. The bile canaliculi empty into a series of progressively larger bile ductules and ducts, which eventually become common hepatic duct. The bile canaliculi empty directly into the Canals of Hering. Hepatocytes are polyhedral in shape, therefore having no set shape or design, although they are made of cuboidal epithelial cells. They have surfaces facing the sinusoids, (called sinusoidal faces) and surfaces which contact other hepatocytes. The interlobular bile ducts (or interlobular ductules) carry bile in the liver between the Canals of Hering and the interlobar bile ducts. They are part of the interlobular portal triad and can be easily localized by looking for the much larger portal vein. The cells of the ducts are described as cuboidal epithelium with increasing amounts of connective tissue around it., (called lateral faces). Bile canaliculi are formed by grooves on some of the lateral faces of these hepatocytes. Microvilli are present in the canaliculi. The canals of Hering, or intrahepatic bile ductules, are part of the outflow system of exocrine bile product from the liver. Liver stem cells are located in the canals of Hering. The interlobular bile ducts (or interlobular ductules) carry bile in the liver between the Canals of Hering and the interlobar bile ducts. They are part of the interlobular portal triad and can be easily localized by looking for the much larger portal vein. The cells of the ducts are described as cuboidal epithelium with increasing amounts of the connective tissue around The interlobular bile ducts (or interlobular ductules) carry bile in the liver between the Canals of Hering and the interlobar bile ducts. They are part of the interlobular portal triad and can be easily localized by looking for the much larger portal vein. The cells of the ducts are described as cuboidal epithelium with increasing amounts of connective tissue around Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver. They can be divided into: Lobar ducts (right and left hepatic ducts) - stratified columnar epithelium. Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium. Interlobular bile ducts (between the interlobar ducts and the lobules) - simple columnar epithelium. Intralobular bile ducts (cholangioles or Canals of Hering) - simple cuboidal epithelium, then by hepatocytes Bile canaliculi - two half-canaliculi formed by the hepatocytes facing the perisinusoidal space. The common hepatic duct is the first part of the biliary tract. It joins the cystic duct coming from the gallbladder to form the common bile duct. The cystic duct is the short duct that joins the gallbladder to the common hepatic duct. It usually lies next to the cystic artery. It is of variable length. It contains 'spiral valves of Heister', which do not provide much resistance to the flow of bile. In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct, and releases it via the common bile duct into the duodenum, where the bile helps in the digestion of fats. The common bile duct, sometimes abbreviated as CBD, is a duct in the gastrointestinal tract of organisms that have a gallbladder. It is formed by the confluence of the common hepatic duct and cystic duct and terminates by uniting with pancreatic duct, forming the ampulla of Vater. The flow of bile from the ampulla of Vater into the duodenum is under the control of the sphincter of Oddi. When the sphincter of Oddi is closed, newly synthesized bile from the liver is forced into storage in the gallbladder. When open, the stored and concentrated bile (now mixed with pancreatic secretions) exits into the duodenum and takes part in digestion. This conduction of bile is the main function of the common bile duct. The hormone cholecystokinin, when stimulated by a fatty meal, promotes bile secretion by increased production of hepatic bile, contraction of the gallbladder, and relaxation of the sphincter of Oddi.

What is Bile pH level?

The hepatic Bile has a pH of about 7.4 and the Bladder bile has a pH of about 6.8. On an average the pH of bile juice is between 6.8 and 7.6.
