Figure 27: Lymph Vessels of the Kidneys and Lymph Nodes Along the Abdominal Aorta and its Terminal Branches

Drawing of the dorsal abdominal cavity and kidneys with associated lymph nodes and lymphatic vessels.

Figure 27: The dog lies on its back, the ventral abdominal wall and the abdominal organs (except for the kidneys) are removed. The kidneys are not drawn in the correct position; the right kidney (f) is pushed back pelvically, so that certain lymph vessels could be drawn into the figure. a, a1, a2 diaphragm; b lumbar musculature; c lateral abdominal wall; d depressor muscles of the tail (muscles that lower the tail) and e lateral flexors of tail; f, f’ kidneys; g caudal vena cava; h abdominal aorta; i right deep circumflex iliac artery and vein; k right external iliac artery and vein; l right hypogastric artery and vein. 1 left and 1′ right cranial lumbar aortic lymph nodes (the latter is covered by the caudal vena cava); 2 lumbar aortic lymph nodes located near the renal artery and vein; 3, 3’ lumbar aortic lymph nodes (those marked [3′] are covered by the caudal vena cava); 4, 41, 42 medial iliac lymph nodes; 5 hypogastric lymph nodes; 6 medial sacral lymph nodes; 7 lateral sacral lymph node; 8, 8′ deep inguinal lymph node; 9 cisterna chyli; 10 pelvic lymphatic trunk; 11 efferent vessels of the superficial inguinal lymph nodes and medial femoral lymph node (some of them [11’] enter the deep inguinal lymph node [8]); 12 lymph vessels which travel with the sympathetic nerve and greater splanchnic nerve from the thoracic cavity into the abdominal cavity; 13 lymph vessels of the diaphragm.
