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, one of which ends in the left renal or suprarenal vein,
The inferior phrenic artery is a bilaterally paired artery of the abdominal cavity which represents the main source of arterial supply to the diaphragm. Each artery usually arises either from the coeliac trunk or the abdominal aorta, however, their origin is highly variable and the different sites of origin are different for the left artery and right artery.
From above, the diaphragm receives blood from branches of the internal thoracic arteries, namely the pericardiacophrenic artery and musculophrenic artery; from the superior phrenic arteries, which arise directly from the thoracic aorta; and from the lower internal intercostal arteries. From below, the inferior phrenic arteries supply the ...

The caval opening of diaphragm [2] (also foramen of vena cava, [1] vena caval foramen [3] [1]) is an opening in the central tendon of diaphragm giving passage to the inferior vena cava [2] [3] as well as to some terminal [2] branches of [2] [1] the right phrenic nerve, [2] [3] and some lymphatic vessels en route to middle phrenic and mediastinal lymph nodes.

The suprarenal veins are two in number: . the right ends in the inferior vena cava.; the left ends in the left renal or left inferior phrenic vein.; They receive blood from the adrenal glands and will sometimes form anastomoses with the inferior phrenic veins.
The renal veins empty into the inferior vena cava, entering it at nearly a 90° angle. [ 1 ] Due to the right-ward displacement of the inferior vena cava from the midline, the left renal vein is some 3 times longer than the right one (~7.5 cm and ~2.5 cm, respectively).
It receives one or two branches from the phrenic nerve. At the point of junction of the right phrenic plexus with the phrenic nerve is a small ganglion ( ganglion phrenicum ). This plexus distributes branches to the inferior vena cava, and to the suprarenal and hepatic plexuses .
