Hepatitis primarily affects which organ in the body?

Hepatitis is a term that specifically refers to inflammation of the liver, which is a vital organ in the body responsible for numerous essential functions, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion. The different types of hepatitis, such as hepatitis A, B, and C, are all viral infections that directly target the liver, leading to its inflammation and, in some cases, serious complications like liver damage or failure. Understanding this relationship is crucial because it highlights the importance of liver health and the potential consequences of liver inflammation due to hepatitis. The other options listed, such as the heart, kidneys, and lungs, are not primarily affected by hepatitis, making it clear that the liver is the correct answer.
