describe the relationship between pancreas and liver

Sep 27, Learn how the liver, gall bladder and pancreas help the body digest gall bladder shares a vessel, called the common bile duct, with the liver. The liver, pancreas, and gallbladder are considered accessory digestive organs, Between adjacent hepatocytes, grooves in the cell membranes provide room for . Describe the location of hepatocytes in the liver and how this arrangement . The pancreas and liver produce juices (pancreatic juice and bile) which help in which exits (along with the pancreatic duct) into the duodenum at the "papilla of Vater. Annular pancreas describes a congenital condition in which one of the.

But if the pancreas is inflamed pancreatitisthey already become active in the pancreas. These groups of cells produce insulin, glucagon and other hormones.

They are called endocrine "secreting internally" cells because the hormones that they produce are secreted directly into the blood. These hormones usually help to regulate blood sugar levels, stopping them from getting too high or too low. When the blood sugar levels rise, as they do after a meal, insulin is released by the islets of Langerhans. This hormone helps sugar to be absorbed from the bloodstream into the cells of the body. Insulin also allows the liver and the muscles to store sugar, as well as keeping the liver from producing more sugar.

This lowers your blood sugar levels. When blood sugar levels are too low, the pancreas releases glucagon into the bloodstream. This hormone does the opposite of what insulin does: It causes the liver cells to release stored sugar.

It also makes sure that proteins in the liver are turned into sugar that can then be used for energy. Like a river, these ducts gradually join together to form one stream in the main bile duct, which exits along with the pancreatic duct into the duodenum at the "papilla of Vater. The anatomy design of the biliary and pancreatic ducts is not the same in every person. Variations can be important; some can cause medical problems, others may make treatment more difficult or complicated.

Papilla of Vater and Minor Accessory Papilla The main papilla of Vater is a small nipple-like structure on the wall of the duodenum, in its "second part. The papilla forms the main exit hole for the bile and pancreatic juices which flow down the bile duct and pancreatic duct. Rarely there are two separate holes close together within the same papillary nipple.

The papilla remains closed at rest, because of the activity of a muscular valve sphincter. The sphincter of Oddi surrounds the exit of the bile duct and pancreatic duct. It opens by reflex action when foods enter the stomach, so that juices can be released to help in their digestion. This is the exit hole for Santorini's duct.

The minor papilla occasionally acts as a useful safety valve when the main papilla is not able to function correctly, but becomes the main site of drainage for pancreatic juices in the congenital variant called pancreas divisum. Bile Duct System and Gallbladder The bile duct biliary system provides the channels through which bile is transported from the liver to the duodenum through the papilla of Vater.

Anatomy of the Liver, Gallbladder & Pancreas

The liver is found in the right upper corner of the abdomen, immediately below the diaphragm. In health it weighs pounds. It is divided into right and left lobes, and each of these have several segments.

The bile ducts start as tiny tubes called sinusoids which lie between rows of liver cells called hepatocytes. These liver cells make bile, and pass it into the tiny canals cannaliculi.

The small ducts join together like branches to form the main biliary tree, with one trunk which is formed just outside the surface of the liver. This is called the common hepatic duct.

The gallbladder is a collection sac for bile, which enters and leaves through a narrow tube called the cystic duct. The gallbladder is about the size of an egg when full. The bile duct below the cystic duct is usually called the common bile duct. The common bile duct and the common hepatic duct together constitute the main bile duct. The lower end of the bile duct sweeps around behind the duodenum and through the head of the pancreas before joining the pancreatic duct at the main papilla of Vater.

Pancreatic Duct System There is a main pancreatic duct which collects juices from all the branches of the pancreatic stream, and exits at the main papilla of Vater. It has functions both in the digestive system and the endocrine system. The pancreas is about Pancreatic tissue is made up of grapelike clusters of cells that synthesize a clear liquid called pancreatic juice, which reaches the duodenum through the common bile duct which is also used by the liver to secrete bile.

It contains three very important enzymes: Among the enzyme producing acinar cells, endocrine cells are present in clusters called the islets of Langerhans. Beta cells are the cells that make insulin, and alpha cells make glucagon. Glucagon These hormones insulin and glucagon work together to regulate blood sugar.
