Hepatic lymph nodes

Hepatic Lymph Nodes

The Hepatic Lymph Nodes are a group of lymph nodes located in the abdomen, specifically around the liver. They play a crucial role in the body's immune system, filtering harmful substances from the lymph fluid before it returns to the bloodstream.

Anatomy

The hepatic lymph nodes are located in the hepatic portal system, which is a network of veins that carry blood from the gastrointestinal tract and spleen to the liver. There are typically three to six hepatic lymph nodes, and they are usually found near the hepatic artery and portal vein.

Function

The primary function of the hepatic lymph nodes is to filter lymph, a clear fluid that contains white blood cells, from the liver. This process helps to remove bacteria, viruses, and other harmful substances from the body. The filtered lymph then returns to the bloodstream via the thoracic duct.

Clinical Significance

Enlargement of the hepatic lymph nodes, known as hepatomegaly, can be a sign of various medical conditions, including liver disease, cancer, and infections. Therefore, examination of the hepatic lymph nodes can provide valuable information in the diagnosis and treatment of these conditions.
