Lymph nodes are knots in the net of lymphatic vessels that serve as filtering stations through which lymph percolates on its way to the blood stream. Lymph nodes are numerous and are found everywhere in the body. Lymph nodes filtering lymph from a particular region or organ are often referred to as regional or draining lymph nodes because all material and cells transported out of a certain region have to pass through a certain lymph node packed with B lymphocytes, T lymphocytes and dendritic cells.
