What is the "lymphatic system"?
If you remember back to high school and college biology, the lymphatic system is another one of those systems that run parallel to the venous and the blood system. Parallel to the blood and the veins and the arteries is the lymph and it's just another way of circulating immune system throughout your body. It's where the B cells and T cells are which help function to control disease and to control infection circulate through the body. It's a parallel system. So, if you usually have a problem with a blood vessel you don't have a problem with the lymph system, and if you have a problem with the lymph system it doesn't necessarily lead to a problem with the blood system. However, ultimately, the lymphomas and the diseases that that arise from the lymphatic system arise within the lymph nodes. Lymph nodes are, the best way to describe them, is that they are draining points along the lymphatic system where B cells and T cells are produced, or your immune system is produced and regulated, as well as where things go awry. Arid T cells and B cells are formed into malignant forms of themselves and that's from where these lymphomas arise.
