Hepatitis B primarily causes inflammation in which organ?

Hepatitis B primarily causes inflammation in the liver because it is a viral infection that specifically targets liver cells. The hepatitis B virus (HBV) is transmitted through contact with infectious body fluids, which can lead to both acute and chronic liver disease. When the virus infects the liver, it triggers an immune response that results in inflammation, leading to symptoms such as jaundice, fatigue, and abdominal pain.

The liver's critical role in processing nutrients, producing bile, and managing toxins emphasizes the importance of this organ in the context of hepatitis B. Chronic infection can result in complications such as cirrhosis and liver cancer, further highlighting the liver's vulnerability to this virus. This specificity of the virus for liver tissue underlies why it is commonly associated with liver inflammation and disease.
