Located in the upper right portion of the abdomen, the liver and gallbladder are interconnected by ducts known as the biliary tract , which drains into the first segment of the small intestine the duodenum.

The gallbladder is a pear-shaped organ that stores about 50 ml of the bile produced by the liver until the body needs it for digestion. It is about 7—10cm long in humans and is dark green in color. The gallbladder has a muscular wall that contracts in response to cholecystokinin, a peptide hormone that is synthesized by the small intestine. When food containing fat enters the digestive tract, the secretion of cholecystokinin CCK is stimulated, and the gallbladder releases the bile into the small intestine. The bile emulsifies fats and neutralizes acids in partly digested food.
The gallbladder is a gastrointestinal organ located within the right hypochondrial region of the abdomen. This intraperitoneal, pear-shaped sac lies within a fossa formed between the inferior aspects of the right and quadrate lobes of the liver. The primary function of the gallbladder is to concentrate and store bile which is produced by the liver. As part of the gustatory response, the stored bile is then released from the gallbladder in response to cholecystokinin. In this article, we shall look at the anatomy of the gallbladder — its structure, vasculature, innervation and lymphatic supply. The gallbladder is entirely surrounded by peritoneum , and is in direct relation to the visceral surface of the liver.

The biliary system consists of the organs and ducts bile ducts, gallbladder, and associated structures that are involved in the production and transportation of bile. When the liver cells secrete bile, it is collected by a system of ducts that flow from the liver through the right and left hepatic ducts.
Can hold 50 ml of bile. The Gallbladder is a small, pear-shaped organ in the abdomen. Its job is to store and release bile, a fluid made by the liver. Bile helps break down fats in the food you eat. A small amount of bile is also sent to the gallbladder for storage. The gallbladder concentrates the bile by removing the water. When bile is needed to digest fats, hormones chemical messengers signal the gallbladder to squeeze bile out through the cystic duct.
ANATOMY AND PHYSIOLOGY OF GALLBLADDER
The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract.
Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder Figure Figure numbers may need to be reordered as well, especially in the printed text. The digestive role of the liver is to produce bile and export it to the duodenum.

То, что Хейл мог его угадать, было исключено: число комбинаций составляло тридцать шесть в пятой степени, или свыше шестидесяти миллионов. Однако в том, что команда на отпирание действительно вводилась, не было никаких сомнений. Сьюзан в изумлении смотрела на монитор.
