Submental Lymph Nodes Functions
The submental lymph nodes drain all debris and waste substances from the teeth, the lower lip, the mouth floor and other regions of the oral cavity.

Submental lymph cells are contained in capsule-like fibers. Some are located just beneath the skin while others lie deep in the body. Just like other lymph nodes, submental lymph nodes play an important role in the immune system. Their function is to filter lymph substances and defend the body against infection by pathogens.

Role of lymph nodes in immunity
Immune action starts in the lymph nodes and spreads to other parts of the body. Like other lymph nodes, submental lymph nodes play a vital role in the normal function of the body’s immune system.

It doesn’t matter the seriousness of the medical condition; they help to fight illness and determine the effectiveness of the treatment given to a person.
Lymphocytes are white blood cells present in all lymph nodes including the submental lymph nodes. These cells help the body’s immune system by fighting the disease-causing micro organisms.
