Hepatic parenchyma refers to the functional tissue of the liver, primarily composed of hepatocytes, which are the main liver cells responsible for various metabolic processes, detoxification, and bile production. This tissue is organized into lobules that facilitate the efficient exchange of substances between the blood and liver cells. The health and functionality of the hepatic parenchyma are crucial for overall liver function and metabolism. Damage to this tissue can lead to liver diseases and impaired metabolic functions.
