It is a crucial component of the lymphatic system, which helps the body fight infections and remove toxins. Some synonyms for lymphatic vessel include lymph vessel, lymphatic capillary, lymphatic duct, and lymphatic channel. These terms are often used interchangeably to refer to the same type of vessel. Other related terms include lymph nodes, which are small, bean-shaped organs that filter lymph, and lymphatic tissue, which includes the tonsils and adenoids.
