Bile (or gall) is a bitter, greenish-yellow alkaline fluid secreted by the liver of most vertebrates. ...


Bile, required for the digestion of food, is excreted by the liver into passages that carry bile toward the hepatic duct, which joins with the cystic duct (carrying bile to and from the gallbladder) to form the common bile duct, which opens into the intestine. Digestion is the process whereby a biological entity processes a substance, in order to chemically convert the substance into nutrients. ... The liver is an organ in vertebrates, including humans. ... ... The cystic duct is the short (usually around a centimetre or so) duct that joins the gall bladder to the common bile duct. ... Gall bladder The gallbladder (or cholecyst) is a pear-shaped organ that stores bile (or gall) until the body needs it for digestion. ... The common bile duct begins at the junction of the common hepatic duct and the cystic duct and ends at the Ampulla of Vater in the second part of the duodenum. ... The intestine is the portion of the alimentary canal extending from the stomach to the anus and, in humans and mammals, consists of two segments, the small intestine and the large intestine. ...


The top half of the common bile duct is associated with the liver, while the bottom half of the common bile duct is associated with the pancreas, through which it passes on its way to the intestine. It opens in the part of the intestine called the duodenum into a structure called the ampulla of Vater. The pancreas is a retroperitoneal organ that serves two functions: exocrine - it produces pancreatic juice containing digestive enzymes endocrine - it produces several important hormones // Anatomy The pancreas is a retroperitoneal organ located posterior to the stomach on the posterior abdominal wall. ... The duodenum is largely responsible for the breakdown of food in the small intestine. ... The Ampulla of Vater is the part of the duodenum where the common bile duct empties into the second part of the duodenum, so named because it has the appearance of an ampulla. ...


Blockage of the bile duct by a cancer or scarring from injury prevents the bile from being transported to the intestine and the bile accumulates in the blood. This condition is called jaundice and the skin and eyes become yellow from the accumulated bile in the blood. This condition also causes severe itchiness. When normal cells are damaged or old they undergo apoptosis; cancer cells, however, avoid apoptosis. ... Red blood cells (erythrocytes) are present in the blood and help carry oxygen to the rest of the cells in the body Blood is a circulating tissue composed of fluid plasma and cells (red blood cells, white blood cells, platelets). ... Jaundice, also known as icterus (adjective:Icteric), is yellowing of the skin, sclera (the white of the eyes) and mucous membranes caused by increased levels of bilirubin in the human body. ... Model of the layers of human skin In zootomy and dermatology, skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. ... This article refers to the sight organ. ...


Jaundice is commonly caused by conditions such as pancreatic cancer, which causes blockage of the bile duct passing through the cancerous portion of the pancreas; cholangiocarcinoma, blockage by a stone in patients with gallstones; and from scarring after injury to the bile duct during gallbladder removal. Pancreatic cancer (also called cancer of the pancreas) is represented by the growth of a malignant tumour within the small pancreas organ. ... Cholangiocarcinoma is an adenocarcinoma of the biliary duct system. ... In medicine, gallstones are crystalline bodies formed within the body by accretion or concretion of normal or abnormal bile components. ...
