• • Kidneys Outer cortex (Dark Stained)
• ● Inner Medulla

  = ○ divided into 8-15 medullary pyramids by extensions of the cortex called cortical columns (renal columns)

  = ○ Medullary rays are straight extensions from the medulla into the cortex
• ● Renal pelvis

  = ○ a central branched chamber which receives the urine & opens into the ureter
• Kidney Functions and Feature

  • Excretion of metabolic waste products
  • Water and electrolyte homeostasis
  • pH homeostasis
  • Renin (released by JG cell) production
  • Vitamin D
  • blood pressure regulation
  • one of the most important organ
  • has a concave medial border, the hilum—where nerves enter, the ureter exits, and blood and lymph vessels enter and exit
  • covered by a thin fibrous capsule
