Document Summary

Function: regulates blood volume and pressure, ph, ion concentrations. Right lower than left supported, protected by layers of ct: renal capsule, adipose + renal fascia protects. Indentation: renal artery, vein, ureter , nerves (enter/exit here) Renal medulla with renal pyramids: each pyramid is separated by downward extensions of cortical tissue = renal columns contain blood vessels. Apex: narrow end of pyramid = renal papilla. Collecting ducts exit at renal papilla -- drain into minor calyx --- 4/5 minor calyces --- major calyx -- 2/3 major calyces --- renal pelvis --- ureter. Renal corpuscle in cortex is the site of blood filtration/ first stop in urine formation: glomerulus = capillary bed, bowman"s capsule completely surrounds glomerulus and drains into tubule, outer layer = simpl. Inner = podocytes (cells wrapped around glomerular capillaries) Filtration membrane: where blood filtered into bowman"s capsule: glomerular endothelium, simp. Sq. with fenestrations (pores: basement membranes, bowman"s capsule, podocytes simp.
