Hepatic lymph nodes

Hepatic lymph nodes are a group of lymph nodes located in the region of the hepatic portal vein and the liver. These lymph nodes play a crucial role in the lymphatic system by filtering lymphatic fluid and facilitating the immune response.

Anatomy

The hepatic lymph nodes are situated along the hepatic artery, the portal vein, and the bile ducts. They are part of the larger network of abdominal lymph nodes and are specifically involved in draining lymph from the liver, gallbladder, stomach, duodenum, and pancreas.

Function

The primary function of the hepatic lymph nodes is to filter lymphatic fluid that originates from the liver and surrounding organs. This filtration process helps in the removal of pathogens, toxins, and other foreign particles. Additionally, these lymph nodes are involved in the activation of the immune response by presenting antigens to lymphocytes.

Clinical Significance

Hepatic lymph nodes can become enlarged or inflamed due to various conditions, including infections, liver diseases, and cancers. Enlargement of these lymph nodes can be detected through imaging techniques such as ultrasound, CT scan, or MRI. Conditions such as hepatitis, cirrhosis, and metastatic cancer can lead to changes in the size and function of the hepatic lymph nodes.
