Renal Anatomy -Surag Khadka

Contents Anatomy of the Kidney Anatomy of the Nephron Anatomy of the glomerulus (Histology)

Kidneys They are retroperitoneal organs (therefore the loin pain) Sits between T11-L2/3 with hilum at L1 Surrounded by: Perinephric fat Renal fascia (Route of infection across the midline) Paranephric fat

Kidney: Internal Structure Cortex Medulla Minor Calyx Major Calyx Renal pelvis Renal Artery Renal Vein Renal pyramid Renal Papilla Ureter R G Tunstall 2013

Nephron Cortical Nephron or Juxtamedullary Nephron (Location difference) Proximal convulated tubule 100% Glucose 70% Water Sodium and Potassium Loop of Henle 20% water (Only in descending) Sodium, potassium (in ascending) Distal convulated tubule Final tuning

Glomerulus

Filtration barrier in glomerulus Capillary endothelium Basement membrane (negatively charged) Podocytes (size dependent)
