Hepatitis C used to require year-long brutal interferon treatments — now 8-12 weeks of pills cures 98% of patients, one of medicine's most stunning success stories. The liver is your largest internal organ and one of only a handful that can regenerate, performing more than 500 essential functions from detoxifying drugs to making bile and clotting factors. This quiz covers anatomy, NAFLD, alcohol, viral hepatitis, transplants, and modern liver medicine.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore liver anatomy and lobules, hepatitis A through E, NAFLD/MASLD and the new drug Resmetirom, alcohol and cirrhosis, acetaminophen toxicity and N-acetylcysteine, transplants and the MELD score, plus genetic conditions like Wilson's disease and hemochromatosis.
NAFLD (Non-Alcoholic Fatty Liver Disease, recently renamed MASLD) is fat accumulation in the liver in people who drink little or no alcohol. It affects roughly a quarter of US adults and is the most common chronic liver disease in developed countries.
Acetaminophen overdose is the leading cause of acute liver failure in the United States. A toxic metabolite (NAPQI) overwhelms the liver's glutathione defenses; the antidote is N-acetylcysteine.
Yes — the liver is one of the few human organs that can regenerate substantially. After surgical removal of up to about 70% of liver mass, hepatocytes can divide and restore function within weeks, the basis for living-donor transplants.
