The liver is a peritoneal organ positioned in the right upper quadrant of the abdomen. It is the largest visceral structure in the abdominal cavity, and the largest gland in the human body. An accessory digestion gland, the liver performs a wide range of functions, such as synthesis of bile, glycogen storage and clotting factor production Liver. Nestled under your diaphragm, above the stomach and right kidney is the largest visceral organ of the human body - the Liver. It has many different functions and plays many different roles from metabolism to digestion to circulation. Traditional Chinese Medicine compares the liver to a military general The two main fissures of the liver are the fissures for the falciform ligament and the ligamentum venosum. However, the liver may also contain accessory and pseudoaccessory fissures. True accessory fissures are rare and are the result of an inward folding of the peritoneum, usually involving the undersurface of the liver
Traditionally, the liver was divided into four anatomical lobes. However, this has been superseded by the use of the Couinaud classification which divides the liver into eight functional units (known as segments), supplied by individual segmental hepatic arteries, portal veins and bile ducts, which can be individually resected Liver surfaces• Divided into 2 anatomical regions: 1.Diaphragmatic surface: Smooth and dome-shaped surface Anterior liver part Inferior to diaphragm Separated from diaphragm by subphrenic recess and from posterior organs {kidney and suprarenal glands} by hepatorenal recess Covered by peritoneum excep lar anatomy of the liver has to be credited to the French surgeon Claude Couinaud [4]. A summary of this work was popularised by two landmark articles by Henri Bismuth [5,6] commonly regarded as the beginning of the era of liver surgery according to anatomical principles. The scheme is based on the concept that the main portal vei

The lobes of the liver are further divided into eight liver segments in the Couinaud system.These are also known as hepatic segments that are surgically resectable.. Left lobe. The left lobe is smaller and more flattened than the right. It is situated in the epigastric, and left hypochondriac regions of the abdomen.Its upper surface is slightly convex and is moulded on to the diaphragm; its. Liver Anatomy Background Assessment of vascular and biliary anatomy and presence of anatomic variants may be important for interventional or surgical planning. Evaluation of hepatic volume can be helpful in estimating functional liver reserve, selecting an appropriate treatment, and determining the prognosis

Lobes of the Liver The lobes of the liver include the left lateral, left medial, right lateral, right medial, quadrate, caudate and papillary Comparative liver macroanatomy •Human - Lobes: Right, left, caudate, quadrate - Majority of liver on R side cranial abdomen - Subdivided into 9 discrete units based on vasculoductular supply - important in surgery • Rodent - Lobes: Right, left, median, caudate - More evenly spaced across cranial abdomen - Rats lack gallbladde
Description. The liver, the largest gland in the body, has both external and internal secretions, which are formed in the hepatic cells.. Its external secretion, the bile, is collected after passing through the bile capillaries by the bile ducts, which join like the twigs and branches of a tree to form two large ducts that unite to form the hepatic duct The liver is a multi-lobed organ that is located at the most forward part of the abdomen. It is so far forward that it lays up against the diaphragm, the muscle that aids in breathing in mammals (birds and reptiles do not have a diaphragm).

Description. The lobules of liver (lobuli hepatis) form the chief mass of the hepatic substance; they may be seen either on the surface of the organ, or by making a section through the gland, as small granular bodies, about the size of a millet-seed, measuring from 1 to 2.5 mm. in diameter..

The venous blood from the GI tract drains into the superior and inferior mesenteric veins; these two vessels are then joined by the splenic vein just posterior to the neck of the pancreas to form the portal vein. This then splits to form the right and left branches, each supplying about half of the liver Anatomy And Physiology Of The Liver Anatomy and Physiology of the Liver The Liver is one of two principal accessory organs of the digestive system. Its metabolic capabilities is so crucial for maintaining several of the body's critical functions that a wide array of physiologic disturbances occur when there is damage to the liver Surface markings and internal vascular (including biliary) anatomy are two different ways by which the liver might be divided. These different methods should not be mixed in describing the several levels of division of the liver (e.g. one level by internal anatomy and another by surface markings); the terminology of the anatomical divisions should be based completely on internal anatomy Anatomy: 7 - 10 cm long structure that lies on visceral surface of the liver usually between the right lobe and quadrate...

Liver Anatomy Details. The liver is predominantly located in the right hypochondrium and epigastric areas and extends into the left hypochondrium.. External anatomy can be studied better by considering it in the form of surfaces, borders, ligaments and the anatomical spaces (recesses) that surround it Bartholin ultimately decided that the role of the liver was to form bile rather than blood. In 1654, the English physician Thomas Glisson was the first scholar to publish a book devoted exclusively to the Anatomy of the Liver. He continued to wonder about the connections between the liver and the glands Concerning human liver anatomy, there are eight functional segments in it. Within a minute, approximately 1500 ml of blood flows through the liver. This is so to ensure its efficient working. Partly due to its ample blood supply, liver is the prime site for metastatic spread of cancer

It sits on top of the stomach, right kidney, and intestines Blood from the intestines that enters the hepatic portal system is rich in nutrients from digested food. The liver alters some of these substances for instant use and stores others.5,7. There are two main venous tributaries - smaller branch veins that drain blood into a larger vein - of the hepatic portal vein Hashtags#LiverLigaments #LiverRelations # MedTe The liver is composed of numerous functional units called lobules. Within each lobule, epithelial cells called hepatocytes are arranged in layers that radiate out from a central vein. Hepatic sinusoids are spaces that lie between groups of layers, while smaller channels called bile canaliculi separate other layers

ANATOMY The liver is the largest solid organ in the body, weighing about 1.5 kg in the adult. Lies in the right upper quadrant of the abdomen and is completely protected by the thoracic rib cage. Completely surrounded by a peritoneal membrane, known as Glisson's capsule Gross Anatomy. Figures 1-13 depict the gross anatomy of the pancreas and its relationship to surrounding organs in adults. It is customary to refer to various portions of the pancreas as head, The portion nearest the liver lies in a groove on the dorsal aspect of the head. ascites - where liver disease cause a build-up of body sodium ('salt'), which leads to fluid retention in the abdominal cavity. Fluid retention in the legs, feet and back may also occur. This is called oedema; liver failure - the liver cells are destroyed faster than the liver can replace them, until the organ can no longer function. The liver occupies the highest part of the abdominal cavity. It's just beneath the diaphragm, which is here. Much the greater part of the liver lies to the right of the midline. Since the liver doesn't usually come below the costal margin, which is here, we can't get a view of it from in front by just removing the anterior abdominal wall Liver cords form columns around the interlobular bile capillary. The cell arrangement is simpler than in mammals. The sinusoids anastamose freely. There are Kupfer cells present. Fibres include, reticular fibres to support the liver cords and elastic fibres in the capsule and vessels. Links. Click here for more information on Liver - Anatomy.
