What are phrenic arteries?
What are phrenic arteries?
The inferior phrenic artery is a paired vessel that arises from the abdominal aorta. Both arteries course over the abdominal surface of the diaphragm and give off several collateral branches that supply the inferior diaphragmatic surface, esophagus, trunk wall and suprarenal glands.
Is there a phrenic vein?
The inferior phrenic veins drain the diaphragm and follow the course of the inferior phrenic arteries; the right ends in the inferior vena cava; the left is often represented by two branches, while the other passes in front of the esophageal hiatus in the diaphragm and opens into the inferior vena cava.
What is the function of phrenic artery?
Function. The inferior phrenic arteries supply the diaphragm. Each of the smaller vessels give 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.
Where is the phrenic veins?
Generally, the vein has its origin above the diaphragm near the apex of the heart. After traversing the diaphragm, the vein receives two collateral veins, in front of the left triangular ligament. One is located anteriorly and to the right of the vein, the other one is situated behind and to the left.
Where is the right phrenic artery?
The right inferior phrenic artery passes posterior to the inferior vena cava and then runs anteriorly on the right side of the vena caval foramen. Each divides into medial and lateral branches near the posterior border of the central tendon of the diaphragm.
Where do the phrenic veins drain?
The Inferior Phrenic Veins drain the diaphragm and follow the course of the inferior phrenic arteries. The right ends in the inferior vena cava.
What are renal veins?

Is inferior phrenic paired?
The inferior phrenic arteries (IPAs) are paired branches of the abdominal aorta/celiac trunk supplying the diaphragm. Their importance lies with the fact that the right inferior phrenic artery is the most common extrahepatic arterial supply of a hepatocellular carcinoma.
Where is the adrenal artery?
The adrenal arteries are arteries in the human abdomen that supply blood to the adrenal glands. The adrenal glands receive input from three different arteries on both the left and right sides of the body: superior suprarenal artery branching from the inferior phrenic artery.
