Lymphoma
M.A.L.T. stands for and is found…
Mucosa-associated lymphoid tissue, which are clusters of lymph tissue within the walls of digestive, respiratory and urinary tracts.
What are the two major drainage routes for lymphatic fluid?
- right lymphatic duct, drains the upper right portion of the body, returning lymph to the bloodstream via the right subclavian vein
- thoracic duct, drains the rest of the body into the left subclavian vein.
