General information
The kidneys are used to excrete fluids and detoxify the body. The adrenal glands are an important hormone producing (endocrine) organ in the body.
Arterial supply
The right or left kidney is supplied by the right or left renal artery (Arteria renalis dextra/sinistra). Venous drainage is provided by the right and left renal veins (renal artery dextra/sinistra), which both flow into the inferior vena cava. The adrenal gland is supplied by three arteries.
The upper adrenal artery (Arteria suprarenalis superior) originates from the lower diaphragmatic artery (Arteria phrenica inferior), the middle adrenal artery (Arteria suprarenalis medialis) originates directly from the aorta and the lower adrenal artery (Arteria suprarenalis inferior) from the right or left renal artery (Arteria renalis dextra/sinistra) (vascular supply kidney). The venous outflow of the right or left adrenal artery is via the right or left adrenal vein (suprarenal artery dextra/sinistra) into the right or left renal vein (renal artery dextra/sinistra) (vascular supply kidney).
