Document Summary

16: urine formation: tubule, glomerular filtration, afferent arterial receives blood that has passed through glomerulus collecting tubes glomerular capsule, specialized for filtration, high pressure forces fluid and small solutes out of blood and into. Peritubular capillaries beds: arise from afferent arterial of glomerulus, normal, low pressure capillaries, adapted for absorption instead of filtration, cling close to renal tubule to reabsorb some substances from. Renal corpuscle: bowman"s capsule (inflow and of renal tubules) & glomerulus (tuft of capillaries, site of filtration movement from capillaries to tubules. Reabsorption in proximal tubule: proximal tubule is a mass absorber, non-regulated reabsorption, microvilli have large surface area, approximately 70% water and sodium reabsorption, 100% glucose reabsorbed. Excretion rate: amount of substance excreted = amount filtered + amount, amount excreted depends on 3 factors: Renal handling of solute: amount of solute excreted per minute < filtered load solute was, amount of solute excreted per minute > filtered load solute was.
