Liver And Gallbladder Anatomy

The gallbladder wall lacks the thick muscular layers of the bowel wall but still has a mucosa lamina propria smooth muscle and serosa except on hepatic surface. After you eat a meal a substance called cholecystokinin is secreted by cells in the walls of the duodendum.

Anatomy Of The Liver And Gallbladder

Cholecystokinin simulates the gallbladder to release the stored bile into the small intestine where it emulsifies large globules of fats so theyre easier to digest.

Liver and gallbladder anatomy. Gallbladder and bile ducts the gallbladder is a pear shaped sac under the right lobe of the liver. The liver and gallbladder the digestive function of the liver is to produce bile which is then delivered to the duodenum to emulsify fats. Usually 5 15 cm in length and with a diameter usually 4 mm.

When it is not full of bile the gallbladder is about 3 inches long and 1 inch wide at its thickest part. The gallbladder is a pouch shaped organ that stores bile produced by the liver. It is joined by the common hepatic duct coming from the liver and cystic duct coming from the gallbladder.

Emulsification is the breaking up of fat globules into smaller fat droplets increasing the surface area upon which fatdigesting enzymes lipases can operate. It is joined by the common hepatic duct coming from the liver and cystic duct coming from the gallbladder. The liver consists of several lobes and receives its blood supply mainly from the hepatic portal vein.

The liver and gallbladder are the two accessory organs of the gastrointestinal tract which carry out a multifunctional role that aids digestion and homeostasis. The gallbladder lies under the liver and frequently 70 invades the liver by direct extension. Between meals it stores and concentrates bile which is produced at a constant rate by the liver.
