An Overview of Human Adrenal Dysfunction

ByRichard IG. Holt and Neil A. Hanley

The two adrenal glands are small endocrine glands weighing approximately 8 g and are situated in the retroperitoneum, immediately superior to the kidneys (hence the anatomical name, “suprarenal” gland) where they share, at least in part, the capsule of the kidney. The gland receives its blood supply through a number of small arteries which originate from the dorsal aorta. On the right, the adrenal vein drains directly into the inferior vena cava, whereas the left adrenal vein enters the left renal vein.
