Liver: Anatomy and Functions [1]
The liver is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm, and on top of the stomach, right kidney, and intestines.. Shaped like a cone, the liver is a dark reddish-brown organ that weighs about 3 pounds.
Nutrient-rich blood flows in from the hepatic portal vein. The liver holds about one pint (13%) of the body’s blood supply at any given moment
These lobules are connected to small ducts (tubes) that connect with larger ducts to form the common hepatic duct. The common hepatic duct transports the bile made by the liver cells to the gallbladder and duodenum (the first part of the small intestine) via the common bile duct.

Treasure Island (FL): StatPearls Publishing; 2023 Jan-.. The liver is a critical organ in the human body that is responsible for an array of functions that help support metabolism, immunity, digestion, detoxification, vitamin storage among other functions
Each lobule is hexagonal and a portal triad (portal vein, hepatic artery, bile duct) sits at each corner of the hexagon. The foundation of the lobule is composed of hepatocytes, which have physiologically distinct apical and basolateral membranes
Primary functions of the liver [3]
It is located below the diaphragm in the right upper quadrant of the abdominal cavity. An adult’s liver weighs approximately 3 pounds and extends approximately from the right 5th rib to the lower border of the rib cage.
The working cells of the liver are known as hepatocytes. Hepatocytes have a unique capacity to reproduce in response to liver injury
Although the liver’s ability to react to damage and repair itself is remarkable, repetitive insults can produce liver failure and death.. The liver is a metabolically active organ responsible for many vital life functions
Liver Functions, Location, Anatomy and Disease [4]
It removes toxins from the body’s blood supply, maintains healthy blood sugar levels, regulates blood clotting, and performs hundreds of other vital functions. It is located beneath the rib cage in the right upper abdomen.
– The liver also produces bile, a fluid that helps digest fats and carry away waste.. – The liver consists of four lobes, which are each made up of eight sections and thousands of lobules (or small lobes).
These include removing waste products and foreign substances from the bloodstream, regulating blood sugar levels, and creating essential nutrients. – Albumin Production: Albumin is a protein that keeps fluids in the bloodstream from leaking into surrounding tissue
[Solved] Which one of these is a function of the liver? [5]
UPPSC Staff Nurse Previous Year Paper [Held on 17th December 2017]. – The liver is an organ of the digestive system only found in vertebrates which detoxifies various metabolites, synthesizes proteins, and produces biochemicals necessary for digestion and growth.
– One of the main functions of the liver is to produce proteins secreted into the blood.. – Plasma proteins consist of many known proteins including albumin, fibrinogens, and apolipoproteins.
– Elimination of carbohydrates is with the stool after reaching the colon.. – Bile juice is concentrated and stored in the gallbladder.

The liver: Structure, function, and disease [7]
It carries out over 500 tasks and plays an essential role in digestion. Its roles include detoxification, protein synthesis, and producing digestive enzymes.
This article will cover the main roles of the liver, how the liver regenerates, what happens when the liver does not function correctly, and how to keep the liver healthy.. A person’s liver is in the upper right section of the abdomen and sits below the diaphragm
This ligament is a band of tissue that keeps the liver anchored to the diaphragm.. A layer of fibrous tissue called Glisson’s capsule covers the outside of the liver
Which of the following is not a function of liver? A. Deamination B. Bile storage C. Synthesis of plasma protein D.Storage of fat-soluble vitamin [8]
Hint: The liver is defined as the largest gland of the body that is just below the diaphragm and it is associated with the digestive system. It is divided into two parts and is connected by falciform ligament
Liver helps to synthesise some kind of salt or juice which help in digestion of fats and lipid, liver not help in digestion of complex molecule but also have role in storing of blood glucose when it exceeds in blood, stored in form of glycogen and when it required then it reconvert into glucose and then release into blood.. – Deamination: The liver has an important role in exudating toxins from the body
– Bile storage: Liver helps to synthesise bile juice from hepatic cells, bile enters into the bile canaliculi which empty into small herring’s canals. A pear shape structure located just below the liver, is known as gall which stores the bile juice or bile salts.
Wikipedia [9]
The liver is a major organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for digestion and growth.[2][3][4] In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm. Its other metabolic roles include carbohydrate metabolism, the production of hormones and substances such as glucose and glycogen, and the decomposition of red blood cells.[4]
The gallbladder, a small pouch that sits just under the liver, stores bile produced by the liver which is later moved to the small intestine to complete digestion.[5] The liver’s highly specialized tissue, consisting mostly of hepatocytes, regulates a wide variety of high-volume biochemical reactions, including the synthesis and breakdown of small and complex molecules, many of which are necessary for normal vital functions.[6] Estimates regarding the organ’s total number of functions vary, but is generally cited as being around 500.[7]. It is not known how to compensate for the absence of liver function in the long term, although liver dialysis techniques can be used in the short term
As of 2018[update],[8] liver transplantation is the only option for complete liver failure.. The liver is a dark reddish brown, wedge-shaped organ with two lobes of unequal size and shape
Anatomy and Function of the Liver [10]
The liver is an organ located in the upper right part of the belly (abdomen). It is beneath the diaphragm and on top of the stomach, right kidney, and intestines
Nutrient-rich blood flows in from the hepatic portal vein.. The segments are made up of a thousand small lobes (lobules)
The common hepatic duct transports bile made by the liver cells to the gallbladder and the first part of the small intestine (the duodenum). Bile is a clear yellow or orange fluid that helps digest food.

The Hepatitis C Trust [12]
This section gives an overview about how your liver works and the affect hepatitis C has on it.. The liver is one of the most important organs in your body.
Your liver can hold around one pint (570ml) of blood at any time. Both lobes are further subdivided into around 100,000 smaller lobes (lobules)
– Absorbing nutrients from food and converting them into energy. – Producing hormones that regulate sexual desire and function
Digestive System: Function, Organs & Anatomy [13]
Your digestive system is a network of organs that help you digest and absorb nutrition from your food. It includes your gastrointestinal (GI) tract and your biliary system
Your biliary system is a network of three organs that deliver bile and enzymes through to your GI tract your bile ducts.. The organs that make up your GI tract, in the order that they are connected, include your mouth, esophagus, stomach, small intestine, large intestine and anus.
Your digestive system is uniquely constructed to do its job of turning your food into the nutrients and energy you need to survive. And when it’s done with that, it handily packages your solid waste, or stool, for disposal when you have a bowel movement.
Liver anatomy [14]
The liver is a large organ found in the upper right quadrant of the abdomen. It is a multifunctional accessory organ of the gastrointestinal tract and performs several essential functions such as detoxification, protein synthesis, bile production and nutrient storage to name only a few
It works synchronously with many other organs and contributes to the maintenance of basic homeostatic mechanisms.. The liver is completely covered by visceral peritoneum, with the exception of the bare area, which is where the liver is in contact with the diaphragm.
Ligaments: coronary, left triangular, falciform, round ligament, venous. Fissures and recesses: porta hepatis (central fissure), subphrenic recess, hepatorenal recess
