Which arteries supply the adrenal glands?

The adrenal glands, located on top of each kidney, receive their blood supply from multiple arteries known as the suprarenal arteries. The three sets of arteries that supply the adrenal glands are the superior, middle, and inferior suprarenal arteries.

The superior suprarenal arteries primarily branch off from the inferior phrenic arteries, which originate from the abdominal aorta. The middle suprarenal arteries derive directly from the abdominal aorta itself, providing essential blood supply. The inferior suprarenal arteries branch from the renal arteries, which facilitate the blood flow to the lower parts of the adrenal glands.

This comprehensive supply from bilateral superior, middle, and inferior suprarenal arteries ensures that the adrenal glands receive adequate blood to perform their vital functions, such as hormone production (including cortisol, aldosterone, and adrenaline). Hence, this answer accurately reflects the anatomy of the vascular supply to the adrenal glands, making it the correct choice.
