Arteries of the Adrenals

Adrenal Blood Supply
There are three adrenal arteries – the superior that arises from the inferior phrenic artery, the middle that arises directly off the aorta and the inferior that arises from the renal artery usually as a branch of the capsular artery. This schematic only shows 3 branches per vessel, but in reality there is extensive branching before each artery actually enters the gland.

The dominant area of arterial supply is the cortex, and the dominant area of venous drainage is the medulla. (Image courtesy of Ashley Davidoff M.D.) adrenal blood supply histology anatomy
