Liver 

Liver Functions

  • detoxification
  • Metabolism
  • Immune system
  • protein synthesis
    • blood clotting factor
  • production of bile
    • Gi anti-microbial
  • Blood sugar balance
    • storage of glycogen
  • Storage of Micronutrients
  • production cholesterol
  • conjugation: hepatocytes combine bilirubin( produces by red blood cells) with glucuronic acid to make it water soluble
    • excretes in the intestine → poop + urine and gives it the color
  1. conjugation process

Symptoms of Chronic Liver Failure

  • Encephalopathy → toxification of blood→ body
  • build filled belly → ascites
    • increased pressure in the portal vein cause fluid to leak from blood vessels into the peritoneal cavity and cause edema → fluid-filled belly
    • treatment:
      • build a bypass
      • paracentesis (removal of the fluid from the abdomen with a needle)
      • liver transplant
  • increased bleeding
    • low platelets and clotting factor
  • eyes turn yellow → jaundice → icterus
    • hemoglobin breakdown → bilirubin
    • first in the eyes because its the whitest and very fatty
    • classification of different types of jaundice
  • portal hypertension
    • increased blood flow due to resistance (fibrosis)
  • variceal bleeding
    • due to portal hypertension blood vessels in the esophagus and stomach become enlarged and weakened ( looking like worms) → they can explode
    • shunting
  • red hand palms
  • spider (rashes)
  • edema
  • bilateral enlargement of breast tissue
  • bleeding
    • low amounts of platelets because they are stored in liver
    • pressure on the venus system
    • liver makes clotting factor → less clotting factors in bloody
    • too many blood cells
    • stones in are in duct
      * turn yellow
      * the stool is less yellow
  • Gynecomastia: bilateral enlargement if the male breast tissue
    • in liver failure
    • the liver fails to metabolize estrogen, this hormonal imbalance causes the breast development
  • Jaundice
    • Three types:
  • Why is jaundice more common in babies?
    • they have higher red blood cells than adults
    • the life span of erythrocytes is shorter( different hemoglobin)
    • the liver is not as good at conjugation yet
    • bowel movements are slower in babies than in adults
    • Treatment:
    • Phototherapy: UV lights make bilirubin water soluble

@@Hepatitis@@

  • most common cause of hepatitis and progression?
    • Viral infection → becoming chronic
    • hepatitis a+b+c+d +e

Hepatitis Virus

  • symptoms for liver infection?
    • → same as liver failure symptoms

Characteristics:

Hepatitis Virus%%Type of Virus%%%%Genetic Material%%%%Transmission%%%%Treatment%%
{{Hepatitis A{{HAVSingle-stranded RNAplayground Fecal-oral route, contaminated food or waterNo specific treatment, usually resolves on its own“least lethal”
{{Hepatitis B{{HBVDouble-stranded DNABlood, semen, vaginal fluids, and other bodily fluidsAntiviral medications, immune modulators, and/or liver transplant
{{Hepatitis C{{HCVSingle-stranded RNABlood-to-blood contactAntiviral medications, immune modulators, and/or liver transplant
{{Hepatitis D{{HDVSingle-stranded RNABlood-to-blood contact, can only infect individuals who are already infected with HBVAntiviral medications and/or liver transplant
{{Hepatitis E{{HEVSingle-stranded RNAPlayground Fecal-oral route, contaminated food or waterNo specific treatment, usually resolves on its own

==Target Areas for Antiviral Medication==

  • Inhibit the virus from invading the host by not letting the virus produce proteins that help them evade the immune system

  • prevent viral assembly of proteins by inhibiting viral enzymes involved in the process of replication

  • genome replication

  • polyprotein processing

  • attachment to the cells

  • inhibition in the assembly process of virus

  • inhibition of molecular structure
