Document Summary
Maintenance of constant solute concentration and constant ph homeostatic regulation of. Maintenance of constant uid volume important for bp and co. Three distinct regions: the cortex, medulla, and pelvis. Renal cortex is the most super cial region. Consists of renal corpuscle (located in renal cortex) and renal tubule (begins at cortex, passes into medulla, then back to cortex) (or bownman"s capsule) Consists of tuft of capillaries called glomerulus and hollow structure called glomerular capsule. Glomerular capsule surrounds glomerulus and is continuous with renal tubule. Main function: production of ltrate glomerulus endothelium is fenestrated, making capillaries extremely porous. Allows for solute-rich but protein-free uid to pass from blood into capsule. Plasma-derived uid or ltrate is the materials renal tubules process to form urine. Parietal layer plays no part in ltrate formation. Visceral layer consists of modi ed, branching epithelial cells called podocytes, terminates in.
