Hint:The inferior phrenic artery is paired with a 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 diaphragm surface, Esophagus, trunk wall and suprarenal glands.
Complete answer:
The blood supply to the diaphragm from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal arteries. The superior phrenic arteries arise from the thoracic duct.
The superior phrenic artery is a small paired artery that arises from the anterior aspect of the lower part of the thoracic aorta, and just before it passes through the aortic hiatus of the diaphragm. The superior phrenic artery supplies the posterior part of the superior surface of the diaphragm.
The lateral branch passes toward the side of the thorax, and anastomoses with the lower intercostal arteries, and also with the musculophrenic . The lateral branch of the right phrenic gives a few vessels to the inferior vena cava.
And the diaphragm is basically innervated by the phrenic nerve which is formed from the cervical nerves. The diaphragm receives blood from the branches of the internal thoracic arteries and from the superior phrenic arteries. The inferior phrenic arteries supply blood from below.
Thus, the correct answer is option (A).
Note:Phrenic arteries arise from the aorta and supply to the diaphragm. The inferior phrenic arteries supply the diaphragm. And they arise either from the aorta or from the celiac artery. The superior phrenic arteries arise from the lower part of the thoracic aorta and they join with the musculophrenic and pericardiacophrenic arteries.
