The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
The gastrointestinal wall can be affected in a number of conditions. An ulcer is something that's eroded through the epithelium of the wall. Ulcers that affect the tract include peptic ulcers and perforated ulcer is one that has eroded completely through the layers. The gastrointestinal wall is inflamed in a number of conditions.
The function of the common bile duct is to allow bile to travel from the gallbladder to the small intestine, mixing with pancreatic digestive enzymes along the way. [4] One possible complication of choledocholithiasis is an infection of the bile ducts between the liver and the gallstone lodged in the common bile duct.
The major duodenal papilla (papilla of Vater) is a rounded projection in the duodenum into which the common bile duct and pancreatic duct drain. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion.
The stomach is a muscular, hollow organ in the upper gastrointestinal tract of humans and many other animals, including several invertebrates.The stomach has a dilated structure and functions as a vital organ in the digestive system.
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
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, cancer of the bile ducts; blockage by a stone in patients with gallstones; and from scarring after injury to the bile duct during gallbladder removal.
Its main function is to absorb the products of digestion (including carbohydrates, proteins, lipids, and vitamins) into the bloodstream. There are three major divisions: Duodenum : A short structure (about 20–25 cm long [ 18 ] ) that receives chyme from the stomach, together with pancreatic juice containing digestive enzymes and bile from the ...
