Know About Your Liver
The liver is a large, meaty organ that sits on the right side of the belly in the upper right-hand bit of the stomach pit, underneath the stomach, and on top of the stomach, right kidney, and digestive systems.
Weighing about 3 pounds and molded like a cone, the liver is reddish-brown/dull rosy tan in color and feels rubbery to the touch. Normally you can't feel the liver, because it's protected by the rib cage. Your liver is probably four to five times the size of your fist.
The liver has two large sections, called the right and the left lobes. The gallbladder sits under the liver, along with parts of the pancreas and intestines.
The liver is vital and necessary for survival of human being; the liver and other organs work together to digest, absorb, and process food. There is currently no way to compensate for the absence of liver function (LFT is used to finding them out) in the long term, although new liver dialysis techniques can be used in the short term.
Liver is a kind of reservoir for blood and also its purifier. Liver gets it dual supply of blood from hepatic portal vein and hepatic arteries. The hepatic artery which brings blood rich in oxygen, pumped out from the heart, and the portal vein which brings blood flowing out of the gut, rich in absorbed food material.
The liver holds something like one half quarter of the body's blood supply at any given minute. Blood flows out of the top of the liver through three large veins called the hepatic veins, into a big vein called the inferior vena cava that goes to the heart. Below the liver, where the hepatic artery and the portal vein come in, the bile duct comes out of the liver.
