Although very complicated and complex, the anatomy of the lymphatic system can be summarized in the following way:
Superficial (suprafascial) circulation: it drains the cutis and the sub-cutis, running parallel to the veins and forming a thick superficial anastomotic network;
Deep (subfascial) circulation: it drains the muscles, joints, and tendons; its main branches run along the vascular-nervous bundles; – Visceral Circulation: it drains internal abdominal and thoracic organs. Perforating lymphatic vessels connect the superficial lymphatic circulation with the deep one.
