Kidney anatomy. Cutaway artwork showing the internal structure of a kidney. The kidney,one of a pair of such organs,is part of the human excretory system. It filters waste such as urea from the blood and passes it to the bladder as urine. Blood arrives in the renal artery (red),is filtered through filtering units (nephrons) in the outer area (cortex) of the kidney (shown at top),and then leaves through the renal vein (blue). The waste products drain towards the centre through the renal medulla (seven dark red areas) and into the renal pelvis and into the ureter (cream,lower left). The kidneys also help regulate electrolyte balance | |
