What are signs that something is wrong with your gallbladder?
The gallbladder is a pear shaped organ that is about 7 to 10 centimeters long (3 to 4 inches) and 2 to 3 centimeters wide (about 1 inch). It has the ability to hold about 50 milliliters of bile which can be emptied via the cystic duct (gallbladder duct) into the common bile duct. From here, the bile will empty into the lumen of the duodenum.

What happens to the gallbladder when you eat?
Before you start eating, your gallbladder is full of bile. When you start eating, your gallbladder receives signals to contract and squeeze the stored bile through the biliary tract. The bile eventually finds its way to your largest bile duct, the common bile duct. Bile passes through the common bile duct into the duodenum, the first part of your small intestine, where it mixes with food waiting to be digested. After you eat, your gallbladder is empty and resembles a deflated balloon, waiting to be filled up again.
What is the name of the system that carries bile from the liver?
Your gallbladder is connected to other parts of your digestive system through a series of bile ducts called the biliary tract. The biliary tract (sometimes called biliary system or biliary tree) is a pipe-like system that carries bile from your liver to your small intestine.

What is the splanchnic mesoderm that grows between the heart and the midgut?
Therefore, an organized layer of splanchnic mesoderm known as the septum transversum grows between the heart and the midgut. As the hepatic diverticulum grows, it divides unequally. The larger cranial bud, commits to becoming the liver primordium and the extrahepatic biliary tree.
How does the biliary tree work?
Once the pressure within the biliary tree reaches 10 mm H2O of bile, there is relaxation of the sphincter of Oddi. Therefore, bile can be released from both the gallbladder and directly from the liver via the biliary tree. However, during fasting states, the absence of cholecystokinin results in contraction of the sphincter of Oddi. Increased pressure in the biliary tree results in diversion of bile into the gallbladder where it is stored and concentrated.The endothelial membrane of the gallbladder is equipped with numerous ion channels that actively absorb sodium, chloride and bicarbonate ions. The water molecules subsequently follow the osmotic gradient generated by the ion shift, resulting in concentration of bile. Finally, the gallbladder also produces about 15 – 20 mL of mucus throughout the course of each day.
How much mucus does the gallbladder produce?

Does the gallbladder help digest fat?
In response to signals, the gallbladder squeezes stored bile into the small intestine through a series of tubes called ducts. Bile helps digest fats, but the gallbladder itself is not essential. Removing the gallbladder in an otherwise healthy individual typically causes no observable problems with health or digestion yet there may be a small risk of diarrhea and fat malabsorption.
Where is the gallbladder located?

Where is the gallbladder located?
The gallbladder is a pear-shaped organ located in the right upper quadrant of the abdomen. It measures approximately 7 cm to 10 cm in length and 4 cm in width. Even though the organ is small, it is a common cause of abdominal pain due to gallstones, which often require surgical removal of the organ. Anatomically, the gallbladder is located anteriorly on the undersurface of liver segments IV and V. There are many variants of the anatomy of the biliary system making exact knowledge of these anatomic possibilities crucial when performing gallbladder and biliary surgery. The gallbladder has an inferior peritoneal surface and a superior liver surface. It has no capsule however some authors describe an extension of the liver capsule (Glisson's capsule) covering the exposed surface of the body of the gallbladder. The gallbladder fundus is wide, and as it continues into the main body, it narrows in diameter. The gallbladder body tapers into the infundibulum, which then connects to the neck and cystic duct. At the distal portion of the gallbladder and into the cystic duct are spiral valves of Heister. These valves may be responsible to aide gallbladder emptying with neural and hormonal stimulation. In most people, there is an inferior outpouching of the gallbladder infundibulum or neck called Hartmann's Pouch. Occasionally there is a paucity located at the top of the gallbladder fundus. This is called a Phrygian cap and has no pathologic or surgical significance. [1]
What are the layers of the gallbladder?
The other layers are the lamina propria, smooth muscularis, and serosa. Rotitansky-Aschoff sinuses are deep inclusions from the mucosal layer extending into the muscularis layer. [5]
What is the function of the gallbladder?
The function of the gallbladder is to store bile (30 ml to 50 ml), which is released during the digestive and absorptive processes in the intestine. Contraction of the gallbladder with the release of bile into the biliary tree and duodenum is caused by gastric distension and fatty food content. This stimulates the secretion of cholecystokinin (CCK) from inclusion cells of the duodenum which causes contraction of the gallbladder. Disruption of neuro innervation, blockage of the cystic duct from gallstones, or other etiologies can cause symptoms of chronic or acute cholecystitis. Tests such as a nuclear HIDA (hepatobiliary) scan with CCK, or ultrasound are used to diagnose gallbladder disease. The gallbladder is distensible, and when the cystic duct is obstructed, it can enlarge to twice its size. This may result in infection requiring surgical removal. [6]
What is the diameter of the bile duct?
The short common bile duct travels inferiorly in the hepatoduodenal ligament along with the hepatic artery on the right and the portal vein posteriorly. The normal common bile duct diameter varies from 4 mm to 7 mm. Dilation of this duct usually indicates a distal obstruction from a common bile duct stone, benign stricture or neoplasm of the bile duct, pancreatic head, or ampulla Vater.
What arteries do gallbladders get their blood from?
The gallbladder receives most of its blood supply from the cystic artery. The cystic artery is a branch of the right hepatic artery which arises from the common hepatic artery. Anatomic variants of this vascular supply are also frequently encountered. The common bile duct receives blood from the proper hepatic, the right gastric, the gastroduodenal, and the posterior superior pancreaticoduodenal arteries. These small vessels must be preserved during surgery to ensure adequate perfusion of the cystic and common bile ducts. Disruption of these vessels will increase rates of duct ischemia and leaks. There is no formal cystic vein. Venous drainage is by direct emptying into the gallbladder bed of the liver by short venules from the gallbladder into the liver parenchyma. Larger venous sinuses of the liver can also be encountered during cholecystectomy, and these can be problematic when trying to control bleeding. Subserosal and submucosal lymphatics drain the gallbladder to the cystic lymph node of Lund or node of Calot located in the Calot triangle. Cancer of the gallbladder often bypasses this lymph node and spreads directly to nodes located in the porta hepatis. [3]
Which nerves innervate the gallbladder?
The gallbladder and cystic duct receive innervation from the following three nerves: 1) the right phrenic nerve conveys sensory information, 2) the hepatic branch of the right vagus nerve provides parasympathetic innervation, and 3) the celiac plexus provides sympathetic information. Gastric surgeries such as resections or bariatric procedures, or vagotomies done for peptic ulcer disease will de-innervate the gallbladder and cause dysfunctioning of the organ. This will, in turn, lead to the formation of gallstones and cholecystitis. Many times when such surgeries are performed, prophylactic cholecystectomies are done simultaneously to prevent cholecystitis. [4]
Which muscle prevents reflux of the bile duct?
The distal end of the common bile duct is formed by the union of the pancreatic duct to form the common channel known as the ampulla of Vater. The ampulla of Vater is surrounded by a smooth muscle called the sphincter of Oddi, which prevents the reflux of duodenal secretions into the bile duct.
Which ducts secrete bile?
Hepatocytes synthesize and secrete bile via the right and left hepatic ducts. These ducts fuse into a single common hepatic duct in the lateral part of the porta hepatis. The neck of the gallbladder funnels off into the short cystic duct. This duct combines with the common hepatic duct to form the common bile duct.
Which duct is responsible for the flow of bile and pancreatic juice?
The common bile duct unites with the pancreatic duct to form the ampulla of Vater (hepatopancreatic ampulla), which opens into the duodenum on the major duodenal papilla. The flow of bile and pancreatic juice is controlled by the sphincter of Oddi. Anatomy of the biliary system and gallbladder location: Anterior view.
What are the two organs that help with digestion?
The liver and gallbladder are the two accessory organs of the gastrointestinal tract, which carry out a multifunctional role that aids digestion and homeostasis.
