Q: What are the functions of the gallbladder?Is it related to guts?Answer: The main function of the gallbladder is to store, concentrate and discharge bile, and it also has a certain secretion function, secreting mucinous substances to protect the gallbladder mucosa. In addition, it also has an immune function that can secrete IgA, and after IgA is secreted into the intestine, it combines into double IgA to form an important defense barrier of the intestine. There is no correlation between gallbladder and bile. Q: Can a person live without a gallbladder?
A: Yes. After gallbladder resection, the function of the gallbladder can be gradually replaced by the bile duct without obvious impact, and most of the diseased gallbladder has lost its function, and there is the possibility of repeated infection and cancer.
Q: Is bile produced by the gallbladder?
A: No, it is not. The gallbladder is only an organ that stores bile, which is secreted by liver cells into the intrahepatic bile duct, flows into the extrahepatic bile duct, and enters the gallbladder for concentration. After eating, the gallbladder then discharges bile into the intestines.
Q: What color is bile?Yellow or green?
A: The color of bile is mainly determined by the bilirubin it contains, so normal bile is golden yellow. After it enters the intestine or due to infection, biliary reflux and other factors, bilirubin will be oxidized to biliverdin, so the bile will gradually turn yellow-green or green. In severe cases, the bile will take on a dark green color.
Q: Why are the bile ducts the lifeblood of the human being?
Answer: The bile duct is a pipe for transporting bile, which is composed of capillary bile ducts, intrahepatic bile ducts, and extrahepatic bile ducts, and bile enters the intestine through the bile ducts to play its digestive and other functions, and there is only one pipeline from the liver to the intestines.

The biliary system is made up of organs and ducts that help make and transport bile, including the gallbladder and bile duct system. The gallbladder is pear-shaped, located below the liver, and is connected to the common bile duct by the cystic duct. The bile ducts are usually divided into intrahepatic (located within the liver) and extrahepatic (located outside the liver).
The bile ducts in the liver are called intrahepatic bile ducts, and the bile ducts are the beginning of the bile duct system, and bile secreted by liver cells is discharged directly into the lumen.
The bile ducts converge into the interlobular bile ducts, which converge to form the intrahepatic bile ducts, which then join the left and right hepatic ducts. The left and right hepatic ducts merge into the common hepatic duct after exiting the hepatic portal, and the common hepatic duct and the cystic duct merge into the common bile duct. It's like a trickle of water flowing into the ocean.
The common bile duct is about 6 8 cm long, and the end joins the pancreatic duct and expands to form the ampulla of vater, which opens in the descending duodenum. The opening is surrounded by the ODDI sphincter, which acts as an entrance and exit manager of the biliary tract, effectively controlling bile output and preventing bile reflux.
The main functions of the biliary system include:1Excrete part of the metabolic waste from the liver into the duodenum;2.Assists in the control of bile release. 3.Immune function, IgA can be secreted, and after IgA is secreted into the intestine, it combines into double IgA to form an important defense barrier of the intestine.
The liver produces about 500 to 600 ml of bile per day. It is mainly composed of water and electrolytes, but also organic compounds, including: bile salts, phospholipids (mainly lecithin), cholesterol, bilirubin and other endogenously produced or ingested compounds, such as hormones that regulate gastrointestinal function and drugs ingested by the body or their metabolites. Among them, bilirubin is the degradation product of senescent red blood cells, and heme is modified and processed, which is the pigment that makes bile yellow-green.
Bile salts (bile acids) are the main organic components in bile. The main function of bile is to dissolve the ingested fats and fat-soluble vitamins and promote their digestion and absorption, and this role is mainly played by bile salts.
In addition, bile allows the body to excrete cholesterol and potentially toxic compounds (e.g., bilirubin, drug metabolites).
In the absence of food, about 75 percent of the bile secreted passes from the common bile duct through the cystic duct into the gallbladder. The rest flows directly into the common bile duct into the duodenum.
The gallbladder absorbs up to 90% of the water in bile, which concentrates and stores bile. Under physiological conditions, the gallbladder can reach a volume of 40 to 50 ml.
After eating, especially after eating foods rich in oil and protein, it stimulates enteroendocrine cells to produce cholecystokinin, which causes the gallbladder to contract and relax the oddi sphincter. Stored bile is released into the duodenum to help break down food.
To minimize synthetic consumption, important bile salts are reabsorbed at the end of the ileum and transported back to the liver. After returning to the liver, bile salts are effectively extracted and secreted back into the bile, this process is called the enterohepatic circulation, its significance is to maintain the normal operation of lipid food digestion and absorption, if it is destroyed, on the one hand, it affects the digestion and absorption of lipids, and on the other hand, it is easy to form cholesterol stones.
