The inferior phrenic arteries are two small vessels, which supply the diaphragm but present much variety in their origin.

They may arise separately from the front of the aorta, immediately above the celiac artery, or by a common trunk, which may spring either from the aorta or from the celiac artery. Sometimes one is derived from the aorta, and the other from one of the renal arteries; they rarely arise as separate vessels from the aorta.

They diverge from one another across the crura of the diaphragm, and then run obliquely upward and lateralward upon its under surface.

Each vessel gives off superior suprarenal branches to the suprarenal gland of its own side. The spleen and the liver also receive a few twigs from the left and right vessels respectively.
