| lymphatic trunks - The largest lymphatic vessels that transport lymph to the lymphatic ducts. |
| lymphatics - Larger lymph vessels that are formed when several lymph capillaries join together; also known as lymph veins. |
| lymphedema - A condition that occurs when the lymphatic drainage system is impaired to the extent that the amount of lymphatic fluid within a given area exceeds the capacity of the lymphatic transport system to remove it. |
