Functions of the liver
The liver regulates most chemical levels in the blood and excretes a
product called bile. This helps carry away waste products from the liver.
All the blood leaving the stomach and intestines passes through the liver.
The liver processes this blood and breaks down, balances, and creates the
nutrients and also metabolizes drugs into forms that are easier to use for
the rest of the body or that are nontoxic.
More than 500 vital functions have been identified with the liver.
Some of the more well-known functions include the following:
Production of bile
Production of certain proteins for blood plasma
Production of cholesterol and special proteins to help carry fats through
the body
Conversion of excess glucose into glycogen for storage
Regulation of blood levels of amino acids, which form the building
blocks of proteins
Functions of the liver
Processing of hemoglobin for use of its iron content (the
liver stores iron)
Conversion of poisonous ammonia to urea (excreted in
the urine)
Clearing the blood of drugs and other poisonous
substances
Regulating blood clotting
Resisting infections by making immune factors and
removing bacteria from the bloodstream
Clearance of bilirubin, also from red blood cells.
Functional disorders of the gallbladder and
sphincter of Oddi
• Pain (sharp
( or aching, in right upper quadrant)
• Dyspeptic (bitter
( belching, nausea, vomiting,
flatulence, constipation, diarrhea)
• Nonspecific toxicity
(fatigue, weakness)
DIAGNOSTIC CRITERIA OF FUNCTIONAL DISORDERS OF
THE GALLBLADDER:
Complaints:
- pain in the right upper quadrant, sometimes in the epigastrium,
umbilicus (usually after physical or emotional stress, intercurrent
diseases), possible irradiation in the right shoulder;
- nausea, vomiting bile, bitterness in the mouth, belching,
violations chair (tendency to diarrhea or constipation)
- chronic nonspecific signs of intoxication.
