Study Notes
Liver Function Key Terms and Objectives
- Bile: A fluid produced by the liver, essential for digestion.
- Bilirubin: A yellow pigment resulting from the breakdown of red blood cells.
- Cirrhosis: A chronic liver disease marked by scarring.
- Conjugated bilirubin: Water-soluble form of bilirubin.
- Crigler-Najjar syndrome: Genetic disorder affecting bilirubin metabolism.
- Delta bilirubin: Bilirubin conjugated with glucuronic acid in the blood.
- Hepatic jaundice: Jaundice resulting from liver dysfunction,
- Hepatitis: Inflammation of the liver.
- Hepatocellular carcinoma: Cancer originating in the liver cells.
- Icterus: Yellowing of the skin and eyes due to high bilirubin levels.
- Jaundice: Yellowing of the skin and/or eyes.
- Kupffer cells: Specialized macrophages in the liver involved in immune function.
- Post-hepatic jaundice: Jaundice associated with problems after the liver, often biliary tract issues.
- Pre-hepatic jaundice: Jaundice linked to issues before the liver, often related to red blood cell breakdown.
- Unconjugated bilirubin: Water-insoluble form of bilirubin.
- Uridine diphosphate glucuronosyltransferase (UDPGT): Enzyme crucial for bilirubin conjugation.
- Urobilinogen: A metabolite of bilirubin excreted in the urine.
Liver Anatomy and Function
- Liver Location and Blood Supply: The liver's location and blood supply are crucial for its function.
- Liver Lobules: Lobules are the functional units of the liver.
- Blood Flow Through the Liver: Blood flows through the liver via the hepatic portal vein and hepatic artery.
- Liver Cell Types and Function: Two important cell types in the liver are hepatocytes and Kupffer cells.
- Four Major Functions of the Liver: The liver performs numerous functions; four major ones include carbohydrate metabolism, lipid metabolism, protein metabolism, and detoxification.
- Bilirubin Metabolism Steps: The steps involved in bilirubin metabolism are detailed and critical.
Bilirubin Conjugation and Jaundice
- Unconjugated vs. Conjugated Bilirubin: Explain the differences and importance of conjugation.
- Conjugation Mechanism: The process of bilirubin conjugation in the liver is described.
- Liver Function and Bile Secretion/Detoxification: The role of the liver and bile in the process of secretion and detoxification is highlighted.
- Pre-hepatic, Hepatic, and Post-hepatic Jaundice: The different types of jaundice and their causes are explored.
- Bilirubin Reference Ranges: Age-specific bilirubin reference ranges are considered.
- Total and Direct Bilirubin Measurements: The methods for measuring these are compared.
- Liver Role in Carbohydrate, Lipid, and Protein Metabolism: Detailed descriptions of the roles.
- Liver Role in Detoxification and Drug Metabolism: The significance of detoxification in the liver is expanded upon.
- Clinical Significance of Jaundice and Kernicterus: The significance of jaundice in patients is discussed.
- Causes and Treatment of Jaundice Types: The causes and treatment are explored in detail.
- Genetic disorders associated with Hepatic Jaundice: Genetic causes are examined.
- Light Therapy for Jaundice: The mechanism for how it works in treating jaundice is described.
- Liver Cancer: Information including metastasis, causes and treatments are included.
Liver Function Measurement and Disorders
- Diazo Reaction Principle: This is explained.
- Calculating Unconjugated Bilirubin: A method to calculate this is described if given.
- Bilirubin Fractions: Understanding the fractions of bilirubin in blood is explained.
- Specimen Requirements for Bilirubin Tests: The specifications and preservation processes are detailed.
- Light Protection during Bilirubin Testing: The processes and rationale for light protection during bilirubin tests is discussed.
- Urobilinogen Pathway: The pathway of urobilinogen is described.
- Hepatitis Causes: Common causes of hepatitis are listed.
- Enzyme Markers for Liver Disease: Common enzymes and how they are used to differentiate liver issues.
- Liver Disorders and Diagnosis: Liver disorders and methods for diagnosing them are explicitly presented.
- Laboratory Data Correlations: Correlations with normal or pathological liver findings are explained.
- Comparing Total and Direct Bilirubin Measurements: Comparison of methods for measuring bilirubin, and their use in diagnosis.
- Hepatitis Types: Detailed information about various hepatitis types (causes, transmission, occurrence, alternate names, physiology, diagnosis, and treatment).
- Applying Liver Function Knowledge to Case Studies: How to apply the knowledge gained to case studies in the chapter.
