Below is an organized overview of the liver, covering its structure, functions, diseases, and overall importance. • 1. Anatomy and Location of the Liver • The liver is the largest internal organ in the human body, weighing approximately 1.4 to 1.6 kilograms in adults. It is located in the upper right quadrant of the abdomen, beneath the diaphragm, and is mostly protected by the rib cage. The liver has two main lobes: • Right lobe: Larger of the two, accounts for about 60-70% of the liver’s mass. • Left lobe: Smaller and more tapered, accounting for the rest. • Each lobe is further divided into segments, and these segments contain liver cells called hepatocytes. • 2. Blood Supply • The liver has a unique dual blood supply: • Hepatic artery: Supplies oxygen-rich blood from the heart. • Hepatic portal vein: Brings nutrient-rich but oxygen-poor blood from the gastrointestinal tract, spleen, and pancreas for filtration and metabolism. • 3. Functions of the Liver • The liver performs over 500 functions, but the most critical ones include: • A. Metabolism • B. Detoxification • C. Bile Production • D. Storage • E. Immune Function • 4. Diseases of the Liver • Several conditions can impair liver function, including: • A. Hepatitis • Inflammation of the liver, commonly caused by viral infections (Hepatitis A, B, C) or excessive alcohol use. It can lead to scarring (fibrosis) and liver damage. • B. Cirrhosis • A chronic liver condition characterized by irreversible scarring of the liver tissue due to prolonged damage from alcohol, toxins, or chronic infections. Cirrhosis can progress to liver failure. • C. Fatty Liver Disease • Fat accumulation in the liver, which can be non-alcoholic (NAFLD) or alcohol-induced (AFLD). It can lead to inflammation (steatohepatitis) and cirrhosis if untreated. • D. Liver Cancer • The most common form of liver cancer is hepatocellular carcinoma (HCC). Risk factors include chronic hepatitis, cirrhosis, and long-term alcohol abuse. • 5. Diagnostic Tests • Several tests and imaging studies are used to assess liver function and detect disease: • Liver function tests (LFTs): Measure enzymes (ALT, AST) and proteins (albumin, bilirubin) in the blood. • Ultrasound: Non-invasive imaging to detect liver abnormalities like tumors or fatty liver. • Liver biopsy: Removal of a small tissue sample for microscopic examination. • FibroScan: A non-invasive method to assess liver fibrosis and cirrhosis. • 6. Liver Transplantation • In cases of end-stage liver disease or acute liver failure, a liver transplant may be necessary. Liver transplantation replaces the damaged liver with a healthy liver from a donor. • 7. Liver Health and Prevention • To maintain liver health, it's essential to: • Limit alcohol consumption. • Maintain a healthy weight to avoid fatty liver disease. • Practice safe sex and avoid sharing needles to prevent viral hepatitis. • Get vaccinated against Hepatitis A and B. • Eat a balanced diet rich in fruits, vegetables, and lean proteins. • Stay tuned for more in-depth insights and practical advice on medical and health sciences. • 📌 **Visit our website**: https://clinicside.com/ • *Video Related* • Anatomy and Physiology of the Liver, Animation • Liver Explained!
