Kidney anatomy overview

structure

arterial supply

Direct branches from abdominal aorta
End arteries - obstruction = infarction
Renal artery → segmental arteries→ lobar arteries → interlobar arteries → arcuate arteries → interlobular arteries → afferent arterioles

venous drainage

Directly into IVC

lymphatic drainage

Para-aortic/lumbar nodes

innervation

  • Renal plexus = sympathetic trunk, coeliac plexus, spinal nerves
  • Sensory afferents - T11 - L2

hey what about where the urine gets made

that's in Renal circulation and cortex 1
most of the physiologically active stuff is in the cortex
