The ultrastructures of the hemal node and the hemolymph node in the Korean native goat were observed by transmission and scanning elelctron microscopies for their morphological features. The sinus of hemal node was lined by endothelial-like reticular cells that had an euchromatin-rich nucleus and many cytoplasmic processes by which reticular fibers were surrounded. In the hemolymph node, the mast cell and the plasma cell were closely contact each other by the cytoplasmic process. The hemal node had venous sinusal-like vessels which were different from the deep sinus, and the hemolymph node had lymph capillaries. The lymph vessels with valves were observed in the capsule of the hemolymph node.
