1. Kidney macroscopic structure and regions

Key Concepts & Definitions

  • Retroperitoneal location: Kidneys are positioned retroperitoneally on both sides of the vertebral column.
  • Renal sinus: The renal sinus is the shallow C-shaped space that receives the renal pelvis and calyces through the hilus.
  • Hilus: The hilus is the longitudinal slit on the kidney where vessels and ducts enter or leave.
  • Cortex: The cortex is the outer reddish-brown kidney zone containing mainly convoluted proximal and distal tubules.
  • Medulla: The medulla is the inner paler, striated kidney zone formed by renal pyramids and straight ducts.
