Májszövet
Májszövet, also known as liver tissue, is the primary functional tissue of the liver. It is composed of hepatocytes, which are specialized cells responsible for a vast array of metabolic, endocrine, and exocrine functions. These functions include the synthesis of proteins, detoxification of harmful substances, production of bile, and storage of glycogen and vitamins. The liver tissue is organized into lobules, which are hexagonal structures containing central veins and portal triads at their corners. Each portal triad consists of a branch of the hepatic artery, the portal vein, and the bile duct. Blood from the portal vein and hepatic artery flows through sinusoids, which are capillaries lined by endothelial cells and Kupffer cells (macrophages), and into the central vein. Bile, produced by hepatocytes, flows in the opposite direction through bile canaliculi towards the bile ducts. Májszövet has a remarkable capacity for regeneration, meaning it can repair itself after injury or partial removal. This regenerative ability is crucial for maintaining liver function. Diseases affecting májszövet can lead to a wide range of health problems, including hepatitis, cirrhosis, and liver cancer. Understanding the structure and function of májszövet is essential for diagnosing and treating liver diseases.
