The liver is the most voluminous internal organs of the body and one of the most important in terms of metabolic activity of the organism. Plays unique and vital functions such as protein synthesis (assimilation), production of bile (necessary for digestion and absorption of fats), detoxifying function, vitamin store, glycogen, and so on.
The liver is located in the region of right upper quadrant of the abdomen (usually does not exceed the limit of the costal margin), filling the space diagrammatical dome, where it can reach up to the fifth rib, and relates to the heart through the center phrenic to the left of the inferior vena cava.
Usually it is soft and pitting, and is covered by a fibrous capsule. On this fibrous capsule is applied to the greatest bearing peritoneum of the liver surface (except in the bare area of liver).
Macroscopically is divided into four lobes:
1. Right lobe, the most voluminous.
2. Left lobe, extended on the stomach.
3. Square, at the base, smaller than previous ones, between the fosse of the gallbladder and the round ligament.
4. Caudate lobe, located at the rear of the base of the liver, between the groove of the inferior vena cava and the fissure of venous ligament.
The liver is primarily associated with structures located on the right side of the abdomen, many of which leave an impression on the underside of the right lobe of the liver. Thus we have back and forth the impression colonic, duodenal impression, bonded to the fosse cystic renal printing and less marked. On the underside of the left lobe are printing gastric and esophageal indentation in the rear edge. Relations with the diaphragm and heart surrounding organs complete liver.
The structure of the liver will follow closely the divisions of the portal vein. After the split in segmental branches, the branches of the portal vein, accompanied by the hepatic artery and division of the hepatic ducts, are found together in the portal tract (vein interlobular, interlobar artery and interlobular ducts).
The lymphatic drainage of the liver is provided by vessels that flowed into the inferior vena cava or hepatic lymph following the reverse route of the hepatic artery.
The nerve supply also comes from the celiac plexus that supplies the liver, a mixture of sympathetic and parasympathetic fibers. These nerves reaching the liver along the hepatic artery.
The liver performs multiple functions in the body such as:
* Production of bile: The liver excretes bile into the bile duct and thence to the duodenum. Bile is necessary for the digestion of food.
* Metabolism of carbohydrates:
* Elimination of insulin and other hormones.
* Lipid Metabolism:
Synthesis of cholesterol.
Production of triglycerides.
* Synthesis of clotting factors such as fibrinogen
* Neutralization of toxins, most drugs and hemoglobin.
* Transformation of ammonia into urea.
* Deposit of many substances such as glucose as glycogen, vitamin B12, iron, copper …
* Nonalcoholic steatohepatitis

I’ve been having abdomen pains. Please help me out.?
I’ve been having abdomen pains in all quadrants of my abdomen. The lower left & right quadrants could be Endometriosis, because my mother has it, I’ve been having sudden stabbing pains in my upper left & right quadrants of my stomach now everyday for the week & two days. The doctors pretty much said “screw you, we can’t figure it out, your on your own.” I’ve had an upper G.I & a lower pelvic ultra sound, all my test have come back negative. Can anyone give suggestions about what it could possibly be?
The best suggestion is to find a new doctor – one who will take you seriously and work with you to figure out what the problem is.
Sudden onset is concerning, so please don’t be shy about insisting your doctor (or a preferably a better one) does something about it. If it had been more gradual I would have suspected something dietary (unless you’ve changed your diet recently)Tags: answers, ezine, lang, left, mage, Most Popular, pain, quadrant, source, stomach, stomach pain, stomach pain left upper quadrant, tags, upper, upper quadrant
Recurrent abdominal pain?
For quite a long time, I have had this persistent abdominal pain in the upper and lower quadrants of my left abdomen. Sometimes the pain radiates into my back, the entire left side. Sometimes it goes down to my groin. I have had an abdominal ultrasound which came back normal except for some extra blood in my cul de sac. My doctor doesn’t think that there’s anything seriously wrong with me because my blood came back good and I’ve done a fecal occult test and a digital rectal exam which came back normal. I am scheduled to do an IVP early next year. I don’t think my problem is reproductive as my organs were normal on the ultrasound and the pain is always there, not just during my period. Sometimes its really bad but for the most part it is a dull, throbbing ache. I have no idea what it is and it is worrying me… anyone have any insights.
Also at times there is some itching at certain areas that seem to be under the skin.
My abdominal and pelvic ultrasound showed up normal.
