Bile Duct System (Lab 5 - The Digestive System)

Common bile duct

carries bile from the liver and gallbladder to the duodenum

Bile ductule

collects bile from bile canaliculi

Left hepatic duct

collects bile from left side of liver (from bile ducts)

Right hepatic duct

collects bile from right side of liver (from bile ducts)

Common hepatic duct

collects bile from the left and right hepatic ducts; exits the liver - formed by the convergence of left and right hepatic ducts - joins with the cystic duct to form the common bile duct

Hepatopancreatic sphincter

controls entry of bile and pancreatic juice from the hepatopancreatic ampulla into the major duodenal papilla

Cystic duct (of gallbladder)

converges with the common hepatic duct to form the common bile duct

Main pancreatic duct

duct that drains pancreatic juices into the major duodenal papilla

Hepatopancreatic ampulla

enlarged space where the common bile duct and main pancreatic duct converge

Head of the pancreas

lies in the C-curve of the duodenum - widest part of the pancreas (wide end of the pancreas)

Body of pancreas

middle portion of the pancreas

Bile duct system

1. Left and right hepatic ducts merge to form a common hepatic duct. 2. Common hepatic and cystic ducts merge to form a common bile duct. 3. Main pancreatic duct merges with common bile duct at the hepatopancreatic ampulla, which extends into the duodenum. 4. Bile and pancreatic juices enter duodenum at the major duodenal papilla.

Major duodenal papilla

rounded projection that collects from the common bile duct and the main pancreatic duct and opens into the duodenum

Bile cannaliculi

small tubes between hepatocytes where bile is collected

Tail of the pancreas

tapered end of the pancreas
