Lymph flow in swine. The lymph centre is formed by the inflowing lymph node group to which lymph flow is formed for each tributary area. (A) The parotid lymph centre receives lymph flow from the half-side region of the cranial dorsal side and orbital and masticatory muscles. The superficial cervical lymph centre receives lymph flow from the neck, chest and proximal regions of the forelimbs. (B) The iliofemoral lymph centre receives lymph flow from the flank, dorsal side of the abdominal wall, scrotum and mammary glands. (C,D) Lymph flow and sentinel lymph nodes detected using indocyanine green (ICG). The lymph flow from the right hindlimb to the superficial inguinal lymph nodes was visualized when illuminated with near-infrared light. Lymph nodes illuminated with near-infrared light (E) and white light (F).
