Adrenal artery

Adrenal Artery

The adrenal artery, shown in red, supplies blood to the adrenal glands.

The Adrenal Artery is a blood vessel that supplies the adrenal glands with oxygenated blood. It is a branch of the abdominal aorta, the largest artery in the body. The adrenal artery is divided into three main branches: the superior, middle, and inferior adrenal arteries.

Anatomy

The superior adrenal artery is a branch of the inferior phrenic artery, the middle adrenal artery directly arises from the abdominal aorta, and the inferior adrenal artery is a branch of the renal artery. These arteries supply the adrenal glands, which are located on top of the kidneys.

Function

The adrenal artery delivers oxygenated blood to the adrenal glands. These glands produce hormones such as cortisol, aldosterone, and adrenaline, which are essential for the body's response to stress, regulation of blood pressure, and metabolism.

Clinical Significance

Disorders of the adrenal artery can lead to conditions such as Addison's disease, Cushing's syndrome, and pheochromocytoma. These conditions can cause symptoms such as fatigue, weight loss, and high blood pressure.
