Chapter 38 bookies Flashcards by Shaniya Capre

Functionof liver

-Produces bile ( bile breaks down fats so it can be easily absorbed in digestive tract
-Process nutrients
-regulates blood glucose levels
-Detoxification
-storage energy in form of glycogen
-Protein synthesis
-recycling blood cells

What are things the liver can serve as?

-Blood reservoir- serves as storage and filter
-Metabolism- carbohydrate, fat, protein, fat soluble drugs
-Secretory- bile, bile acids, salts and pigments
-Excretory- Bilirubin, drugs, toxins
-Synthesis -vitamins, carbohydrates, etc
-Storage-Vitamins, carbohydrates, etc

What is bilirubin elimination

Travels to small intestine where it is absorbed into the portal circulation or excreted in feces
-it should not hang out because it is a waste product and should be 100% eliminated

Perfectly

What causes jaudince ?

-Destruction of rbc
-Impaired uptake of bilirubin by liver cells
-Decreases conjugation of bilirubin
-Obstruction of bile flow in the canaliculi of hepatic lobules or in the intrahepatic or extrahepatic bile ducts

**Categories of jaundice
What is prehepatic of jaundice?

Destruction of RBC, body is breaking down rbc quickly
-Bilirubin starts to appear in the blood stream and yellowing of skin, eyes occur

-could be asymptomatic
-Acute hepatitis has specific symptoms
-Carrier state, is when it remains the liver and will be in carrier state

What are signs and symptoms of Hepatitis B?

Study These Flashcards

-Clay colored stool and joint pain
-Loss of appetite
-Nausea
-Vomiting
-Joint pain
-Abdominal pain

How is hepatitis C be trasmitted?

-Blood to blood -Injection drug use -high risk sexual behavior

Describe hepatitis C?

signs and symptoms are very similar to hepatitis B - incubation is about 2-26 days and duration is 2-12 weeks -Immunization does not exist

What is fulminant hepatitis?

Fatalform of Acute form of hep usually b - associated with sever hep B infection -The liver is severely damages and there in no cure -rare but has a few cases

What is intrahepatic biliary disease?

Disease that disrupt flow of bile through the liver which could result in cholestasis and biliary cirrhosis

What causes intrahepatic biliary disease?

-Primary biliary cirrhosis -Primary sclerosing cholangitis -Secondary biliary cirrhosis

What are early symptoms of Intraheptic bilary disease

Unexplained pruritus (itching) Weight loss Fatigue

What are later symptoms of Intrahepatic biliary disease?

-Dark urine and pale stools -Jaundice

What are 3 types of alcohol induced liver disease?

-Fatty liver disease -Alcoholic hepatitis -Cirrhosis

Describe the Alcoholic liver disease

-Liver will start to have more fatty tissue in it -it will have acute inflammation and that will cause scaring so fibrin will build up and make liver stiff -Scaring will lead to Cirrhosis will make the liver stiff and unable to fix -Cirrhosis will eventually lead to liver failure which is not reversible

What is non alcoholic fatty liver disease?

Excess fat deposited into the liver -The fatty deposit disease does not increase unless you make it worse with drinking

What are risk factors of non alcoholic fatty liver disease?

-Co-existing obesity -Type 2 diabetes -Metabolic syndrome -Dyslipidemia -nutritional abnormalities -Surgery,drugs, exposure to toxins

What are signs and symptoms of non alcoholic fatty liver disease?

Usually asymptomatic -Fatigue and upper quadrant paint will be present

What is cirrhosis?

-End stage chronic liver disease -Dense fibrous tissue replaces hepatic tissue -The fibrous tissue leads to scarring and due to the stiff scaring the liver can no longer function

What are signs and symptoms of cirrhosis?

-Melena which is dark tarry stools -Fector hepaticus which would be bad breathe -Esophageal varices is varicose veins in the esophagus -Asterixis which is hand shaking -Diarrhea or constipation -Hepatomegaly -Jaundice -Abdominal pain -Anorexia, weakness, weight loss

What are signs and symptoms of liver failure?

-Hematologic disorders -Endocrine disorders -Skin disorders -Hepatorenal syndrome -Hepatic encephalopathy

What is portal hypertension

increased pressure within the portal venous system

What is primary liver cancer?

Starts in the liver

What is secondary liver cancer/ Metastatic liver cancer?

Cancer that started somewhere else and is affecting the liver

What is hepatocellular carcinoma ?

Most common liver cancer -arise from the liver cells

What can cause hepatocellular carcinoma?

-Viral hepatitis -Cirrhosis -Drug exposure -Water contaminated with arsenic

What are signs and symptoms of Liver cancer?

-Fullness or pain -Abdominal swelling -Weakness -anorexia -Weightloss -Fatigue

What is cholangiocarcinoma?

Primary cancer of bile ducts but rare

What is cholangitis?

Inflammation of common bile duct

What is function of gall bladder

Store and concentrate bile

What is pancreatitis

Inflammation of the pancreas

What are the two types of pancreatitis?

Acute and chronic

What is acute pancreatitis?

Pancreatic ducts becomes obstructed and enzymes back up which causes autodigestion and inflammation of the pancreas

What are signs and symptoms of acute pancreatitis?

epigastric or periumbilical pain radiating to back, chest, or flank; fever; tachycardia; hypotension; severe abdominal tenderness; abdominal distention. Can be mild, severe, or life-threatening | pain will be in upper right quadrant with fever

What is chronic pancreatitis?

Progressive inflammatory disorder that destroys the pancreas. Cells are replaced by fibrous obstructing the pancreatic and common bile ducts

What are signs and symptoms of chronic pancreatitis?

recurring epigastric or upper left quadrant pain; precipitated by alcohol or overeating; anorexia, nausea, vomiting, constipation, flatulence

What are common causes for acute pancreatitis?

-GALLSTONE (stones in the common duct) -Alcohol abuse -HYPERLIDEMIA Hyperparathyroidism Infections (particularly viral) Abdominal and surgical trauma Drugs such as steroids and thiazide diuretics

What is the cause of pancreatic cancer?

UNKNOWN

What are risk factors of pancreatic cancer?

SMoking and diet -High intake of fat, meat, salt -Dehydrated foods, fried foods, refined sugars, soybeans, and nitrosamines

What are signs and symptoms of pancreatic cancer?

dull epigastric pain radiating to dull back pain; worsening pain in supine position relieved by sitting; jaundice; weight loss
