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. Near the back part of the central tendon each vessel divides into a medial and a lateral branch. 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.

The abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of descending aorta (of the thorax).

Path

It begins at the level of the diaphragm, crossing it via the aortic hiatus at the vertebral level of T12.

The aorta (generally pronounced [eɪˈɔːtə] or "ay-orta") is the largest artery in the human body, originating from the left ventricle of the heart and bringing oxygenated blood to all parts of the body in the systemic circulation.

The celiac artery, also known as the celiac trunk and also spelled as coeliac, is the first major branch of the abdominal aorta and branches from the aorta around the level of the T12 vertebra in humans.

The renal arteries normally arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle with the aorta.

The crura of the diaphragm (singular=crus) are tendinous structures that extend downward from the diaphragm to attach to the vertebral column.

In human anatomy, the esophageal hiatus is a hole in the diaphragm through which the esophagus passes. It is located in the right crus of the diaphragm.

It is located approximately at level of the tenth thoracic vertebra (T10).

The inferior vena cava (or IVC) is the large vein that carries de-oxygenated blood from the lower half of the body into the heart.

It is posterior to the abdominal cavity and runs along side of the vertebral column on its right side (i.e. it is a retroperitoneal structure).

The caval opening is a hiatus in the diaphragm of humans through which passes the inferior vena cava, the wall of which is adherent to the margins of the opening, and some branches of the right phrenic nerve.

The central tendon of the diaphragm is a thin but strong aponeurosis situated near the center of the vault formed by the muscle, but somewhat closer to the front than to the back of the thorax, so that the posterior muscular fibers are longer.

The pericardiacophrenic artery is a long slender branch of the internal thoracic artery. It accompanies the phrenic nerve, between the pleura and pericardium, to the diaphragm, to which it is distributed; it anastomoses with the musculophrenic and inferior phrenic arteries.
