Document Summary

Superior lumbar region: from 12 thoracic vertebra to 2nd lumbar vertebra. Adrenal glands sit on top of kidney. Concave medially: renal hilus to renal sinus. Renal capsule: brous, adheres directly to kidney surface, strong barrier. Adipose capsule: cushions, helps hold kidney in place. Renal fascia: dense ct surrounds adrenal gland and kidney; anchoring role. Medulla: darker colour, medullary or renal pyramids; separated by renal columns (cortical tissue); each medullary unit = ~1/8 of kidney. Pelvis: at, funnel shaped tube continuous wit ureter; major and minor chalices; minor chalices enclose papillae of pyramids; chalices collect urine. Walls of chalices, pelvis, ureter contain smooth muscle; propel urine by peristalsis. Pyelitis: uti in ureter or renal pelvis. Arteries: renal artery>>segmental artery>> lobar artery>> interlobar artery>> arcuate artery>> cortical radiate artery. Veins: interlobular vein>> arcuate vein>> interlobar vein>> renal vein. Renal arteries: ~1/4 total systemic co (~1. 2 l) to kidneys/ minute.
