Venous blood is drained from the glands by the suprarenal veins, usually one for each gland: [8] The right suprarenal vein drains into the inferior vena cava. The left suprarenal vein drains into the left renal vein or the left inferior phrenic vein. The central adrenomedullary vein, in the adrenal medulla, is an unusual type of blood vessel.

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.
It is located at the center of the gland, being surrounded by the adrenal cortex. [1] It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines , including epinephrine (adrenaline), norepinephrine (noradrenaline), and a small amount of dopamine , in response to stimulation by sympathetic ...

Schematic of the HPA axis (CRH, corticotropin-releasing hormone; ACTH, adrenocorticotropic hormone) Hypothalamus, pituitary gland, and adrenal cortex The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a ...
The inferior suprarenal artery is a paired artery that supplies the adrenal gland. It usually originates at the trunk of the renal artery before its terminal division, but with many common variations. It supplies the adrenal gland parenchyma, the ureter, and the surrounding cellular tissue and muscles.
