Flashcards in Liver and Biliary Tract Deck (45):
1

Bile ducts exit the liver through the ______.

Hilus

2

The common bile duct joins the pancreatic duct AKA ______

Duct of Wirsung; contained exocrine-digestive enzymes and pH control

3

The hepatic _______ enter the liver carrying nutrients from the small intestine for processing

Portal vein

4

The blood then passes though the liver, and once processed is “dumped” into the __________ for a “trip” to the right side of the heart

Inferior vena cava

5

What are the major liver functions?

1. Excretory: Bile = Bilirubin + Bile Acids
2. Metabolic: Fats, Carbohydrates, Proteins
3. Storage: Carbohydrates & Fats
4. Synthetic: Clotting Proteins, Albumin, transport proteins

6

What is the main indication that the liver is involved with a pathology?

Jaundice

7

Derived from the macrophage destruction of red blood cells that have completed there life span in the liver, spleen, & red bone marrow

Bilirubin

8

Give bile a foamy trait, and are important for digestion of fats in the small intestine

Bile acids

9

Bile acids are reabsorbed from the intestines and transported back to the liver via the portal vein for reuse. This “reuse” circulation of bile acids is called

Enterohepatic circulation of bile

10

Includes abnormal formation, processing , or excretion of bilirubin; yellow discoloration of skin and mucosa; brown or foamy urine with viral hepatitis; itchiness

Jaundice syndromes

11

Inflammation of the liver caused by viruses, drugs, alcohol, and immune mechanisms; often asymptomatic

Hepatitis

12

Injury of liver cells by exogenous chemicals or endogenous metabolites

Toxic/metabolic hepatic injury

End-stage liver disease which may result from many different liver diseases

Cirrhosis

14

Diseases caused by gallstones

Extrahepatic Bile Ducts & Gallbladder Diseases

Occur in the liver and biliary tract, classified as benign, malignant, and primary or secondary (metastasis)

Tumors

16

Bilirubin end product of phagocytosis of senescent red blood cells in the _______ of the liver

Kupffer’s cells

17

Transmitted fecal – oral route, may occur in a sporadic or epidemic form; Symptoms of infection include a short lived mild-fever, vomiting, loss of appetite, and jaundice

Hepatitis A

18

Transmitted via blood transfusions, exposure to contaminated blood or blood products, saliva, semen, or sexual contact; Most prevalent among health care workers, and those working in or around blood products should be inoculated and screened (leads to cirrhosis!); most common form

Hepatitis B

19

What are signs and symptoms of Hep B?

3. Darkening of urine which contains bilirubin
4. Some have measles-like skin rash

20

2nd Major cause of cirrhosis in the U.S. after alcohol abuse

Hepatitis B

21

Transmitted by contaminated blood products, needle sticks, intravenous drug use, contaminated blood transfusions; no vaccine available

Hepatitis C

22

End-stage liver disease; irreversible; incurable except by liver transplant; common causes are alcoholism, Hep B, C, and D, drugs, toxins, bile duct obstruction and inherited abnormalities

Cirrhosis

23

What is the pathophysiology of cirrhosis?

1. Death of liver cells
2. Tissue repair with fibrosis and fibrous bands which obstruct blood flow
3. Regenerative tissue nodules separated by gray scar tissue which restricts blood flow

24

What are the complications in cirrhosis?

1. Ascites (fluid in abdominal cavity)
2. Splenomegaly
3. Thrombocytopenia

25

What are clinical features of cirrhosis?

1. Liver cell injury and necrosis (increase serum liver enzymes)
2. loss of liver fxn
3. Portal hypertension (causes esophageal varicies)
4. Increase of NH4 (causes hepatic encephalopathy, liver flap, numbness, tingling, etc.)

26

What is liver flap (coarse hand tremor) caused by?

excess ammonia (not being broken down)

27

Concretions composed of chemical normally formed in bile and are extremely common

Gallstones, aka Cholelithiasis

28

What are the 2 types of gallstones? which is more common?

1. Cholesterol (more, 75%)
2. Pigmentary (25%0

29

What are the signs and symptoms of gallstones?

1. Excruciating spasmodic pain from cystic duct (immediate duct to gallbladder) obstruction
2. Pain presents within hours of a fatty meal under the right scapula (gallbladder attack)
3. Jaundice (if bile flow is blocked)

30

What are the types of malignant hepatic biliary tumors?

1. Hepatocellular carcinomas (>1 million deaths)
2. Gallbladder cancer (less common, 1% cancer deaths)

31

What are the signs, symptoms and prognosis of hepatocellular carcinomas?

1. Weight Loss
2. Loss of appetite
3. Nausea
4. Painful enlarged liver-compresses other organs
5. Portal hypertension

Poor Prognosis: 5 year survival rate is 10%
