lymphatic system
(lim-FAT-ik SIS-tum)
The tissues and organs that produce, store, and carry white blood cells that fight infection and disease. This system includes the bone marrow, spleen, thymus, and lymph nodes. It also includes the network of thin tubes that carry lymph and white blood cells. These tubes branch, like blood vessels, and pass through all tissues of the body.
