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.

Liver and Gallbladder

Looking at a section of liver is somewhat reminiscent of looking down out of an airplane at a suburban neighborhood. One sees a very regular, almost monotonous, collection of houses in blocks demarcated by roads, with a gas station or minimart apparent at almost every intersection. In the case of the liver, the roads are connective tissue septae which convey vascular and biliary traffic, and the clusters of houses are cord-like arrangements of hepatocytes, the parenchymal cell of the liver. Prior to embarking on the lessons below, it would be best to review the core section Architecture of the Liver and Biliary Tract. Liver: Introduction and Index. Sheets of connective tissue divide the liver into thousands of small units called lobules. A lobule is roughly hexagonal in shape, with portal triads at the vertices and a central vein in the middle.

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. The gallbladder primarily stores, concentrates, and releases bile. The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.

23.5 Accessory Organs in Digestion: The Liver, Pancreas, and Gallbladder

An accessory digestion gland, the liver performs a wide range of functions, such as synthesis of bile , glycogen storage and clotting factor production. In this article, we shall look at the anatomy of the liver — its position, structure, and neurovascular supply. When discussing the anatomical position of the liver, it is useful to consider its external surfaces, associated ligaments, and the anatomical spaces recesses that surround it. Fig 1 — The liver lies in the right hypochondrium of the abdomen, and is surrounded by numerous organs. The external surfaces of the liver are described by their location and adjacent structures. There are two liver surfaces — the diaphragmatic and visceral:.

It is unique among the internal organs for its ability to regenerate following tissue loss. Glucose homeostasis is maintained by the liver by way of glucose storage as glycogen , glycogenolysis, and gluconeogenesis. In addition to glycogen, the liver is an important site for iron, copper, triglyceride, and lipid-soluble vitamin storage.

Using the low power objective observe numerous small, pale spots in the parenchyma, most of which are either central veins or small branches of portal veins in portal canals. There may be a few larger channels, which are larger veins either entering or leaving this region of the liver.

The liver normally weighs between 1. It is the second-largest organ in the body, and is located on the right side of the abdomen. The liver plays a major role in metabolism and has a number of functions in the body, including glycogen storage, plasma protein synthesis, and drug detoxification. It also produces bile, which is important for digestion.

ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота. Я умер. Но я слышу какие-то звуки. Далекий голос… - Дэвид.

Боже. Такой жирный. Крикливый, тучный, мерзкий немец! - Клушар заморгал, стараясь переменить положение, и, не обращая внимания на боль, продолжал: - Ну чистая скотина, килограмм сто двадцать, не меньше. Он вцепился в эту красотку так, словно боялся, что она сбежит, - и я бы ее отлично понял. Ей-ей. Обхватил ее своими ручищами.

Конечно, чтобы придать своему плану правдоподобность, Танкадо использовал тайный адрес… тайный ровно в той мере, чтобы никто не заподозрил обмана. Он сам был своим партнером. Никакой Северной Дакоты нет и в помине. Энсей Танкадо - единственный исполнитель в этом шоу. Единственный исполнитель. Сьюзан пронзила ужасная мысль.

 Травматическая пуля, - задумчиво повторил Беккер.  - Вот откуда шрам. - Весьма сомнительно, чтобы Танкадо связал свои ощущения с выстрелом.

 - Все становится на свои места. Какой-то миг еще ощущались сомнения, казалось, что в любую секунду все снова начнет разваливаться на части. Но затем стала подниматься вторая стена, за ней третья.
