Hepatobiliary System Flashcards
(25 cards)
- largest organ and is sheltered by the ribs in the right upper quadrant of the abdomen
- metabolism, synthesis, detoxification, and storage of substances, including blood clotting and vitamin B storage
Liver
- pear shaped sac
- stores and concentrates bile produced by the liver, receiving it from the hepatic duct and empties it into the duodenum for GI system digestion
Gallbladder
- a system of duct acts to drain bile produced in the liver in the duodenum
Biliary Tree
- short part of the common bile duct
hepatopancreatic ampulla (ampulla of Vater)
- flow of both bile and pancreatic juice into the duodenum
hepatopancreatic sphincter
- elongated, flat organ that obliquely crosses the left side of the abdomen behind the stomach
Pancreas
The hepatobiliary system is composed of
liver, gallbladder, and biliary tree
is used to visualize the biliary tree and involves insertion of a needle into the biliary tree by puncture directly through the wall of the abdomen.
Percutaneous transhepatic cholangiogra- phy (PTC)
This pathology develops as lipids accumulate within the hepatocytes forming free radicals. At some point, the liver cannot rid itself of the excessive triglycerides. This results in an excess of fatty acids within
Fatty Liver Disease
is a chronic liver condition in which the liver parenchyma and architecture are destroyed, fibrous tissue is laid down, and regenerative nodules are formed.
Cirrhosis
is a relatively common liver condition, with an estimated 70,000 cases reported annu- ally in the United States.
Hepatitis
is a single-stranded ribonucleic acid (RNA) picornavirus.
Hepatitis A virus (HAV)
is transmitted paren- terally through infected serum or blood prod- ucts. Its incubation period is much longer (50 to 160 days), and its effects are more severe than those of HAV.
Hepatitis B virus (HBV)
The incubation period of the disease is relatively short (15 to 50 days), and its course is usually mild.
Hepatitis A
is caused by a paren- terally transmitted RNA virus.
Hepatitis C virus (HCV)
is caused by an RNA virus and occurs only concurrently with acute or chronic HBV. It cannot occur alone.
Hepatitis D virus (HDV)
is also an RNA viral agent. It is most commonly responsible for outbreaks of water- borne epidemic acute hepatitis in developing countries.
Hepatitis E virus (HEV)
which has been recently isolated, may also be transmitted via blood products and may cause chronic hepatitis.
Hepatitis G virus (HGV),
acute inflammation of the gallbladder
Cholecystitis
Common in people with diabetes, obese, older adults and individuals who eat a primarily a diet high in saturated fat, sugar, and sodium and low in fiber and nutrient density
Cholelithiasis
an inflammation of the pancreas, can be acute or chronic, with acute cases often resolving without permanent damage while chronic cases lead to irreversible pancreatic changes; diagnosis relies on imaging and laboratory tests, and management includes pain relief, fluid maintenance, and dietary restrictions.
Pancreatitis
-yellowish discoloration of the skin and whites of the eyes
- not a disease itself but rather a sign of disease
- caused by a high level of bilirubin ( a
yellow-ora
Jaundice
-occurs because of hemolytic disease, in which too many red blood cells (RBCs) are destroyed or because of liver damage from cirrhosis or hepatitis. Its most common appearance is transient in the first few days after birth, when more bile pigments are released than can be handled. A liver that is damaged from disease simply cannot excrete the bilirubin in a normal fashion, and it enters the bloodstream.
Medical (nonobstructive)
jaundice
-occurs when the biliary system is obstructed and prevents bile from entering the duodenum. A common cause of this obstruction is blockage of the common bile duct caused by stones or masses. The longer the obstruction persists, the more likely it is that complications (e.g., liver injury, infection, or bleeding) will arise
Surgical (obstructive) jaundice
