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
