Function of the different portions of the nephron

1.      Match the following

a)   Blood filtration, nonspecific filter (filters by size only; good and bad things filtered), removes BOTH useful and non-useful materials into filtrate.

b)   Sac that encloses glomerulus, transfers filtrate from glomerulus----> Proximal Convoluted Tubule (PCT)

c)   Reabsorbs most of the useful substances in the filtrate: Sodium, H2O, HCO3, glucose. Primary site of secretion of toxins, wastes and H+ ions.

d)   Permeable to H2O (water remains), impermeable to solutes(salts)(salt passes). "Saves water and passes salt"

e)   Impermeable to H2O(water passes), actively transports(reabsorbs) salts (NaCl)(salt stays)in the interstitial fluid of the Medulla; " Saves salt and passes water"

f)   If Aldosterone (hormone) is present, Na+ is reabsorbed, (Cl- and H2O follow Na+)

g)   Receives fluid from DCT, if antidiuretic hormone (ADH) is present, collecting duct becomes porous to water. LAST CHANCE to SAVE WATER
