Basic Kidney Anatomy

  • Kidneys paired, about 150 gm each
  • Urine forming units:
    • Cortex
    • Medulla (lobed: renal pyramids)
    • Cortex and medulla composed chiefly of nephrons and blood vessels
    • Supplied by renal arteries (branches of descending aorta) and renal veins (branches of inferior vena cava)
  • Urine collecting and expelling units:
    • Calyces
    • Renal pelvises
    • Ureters
    • Bladder
    • Urethra

Although the Kidneys are Tiny Organs They Receive 25% of the Cardiac Output
