Diseases of the Lymphatic System There are two common disorders affecting the lymphatic circulation — either water retention in tissues due to impaired lymphatic drainage, or swelling of the lymph nodes. The maturation of T-cells as well as the production of antibodies from B-cells is driven by their exposure to pathogens in the lymph nodes.

In this case, the lymphatic system enables our immune system to respond appropriately. These structures express all of the molecular hallmarks of lymphatic endothelial cells, are able to carry both fluid and immune cells from the cerebrospinal fluid, and are connected to the deep cervical lymph nodes. Which of the following systems is matched most accurately to the life function it provides? The lymph nodes filter and absorb pathogens fromthe body. Lymph nodes are round or kidney-shaped, and can be up to 1 inch in diameter.
