The arterial blood supply and venous drainage of the diaphragm in goat was conducted on sixteen specimens. The results revealed that the arterial supply of diaphragm in goat mainly come from the musculophrenic and dorsal intercostal arter-les in addition to small twigs from the cranial ep-igastric, lumber and celiac arteries. The results also revealed that the venous drainage of the dia-phragm drained mainly to the caudal vena cava through right and left phrenic veins in additionlo small tributaries to musculophrenic and crani-al epigastric veins. The distribution of arteries and veins in diaphragm were described in detail and results were discussed with that of the other domestic animals.
