, 90-120 mL/min - ANS what is a nl GFR level?



decreased - ANS decrease renal perfusion= _________ GFR



nephron - ANS basic functional unit of the kidney; processed filtered fluid



glomerulus--> bowman capsule--> PCT --> loop of henle --> DCT --> common collecting duct -
ANS what is the pathway of filtrate though a nephron?



PCT (proximal convoluted tubule) - ANS what reabsorbs 60% of the water from the filtrate
formed and reabsorbs large amounts of Na and K?



Loop of Henle - ANS what controls the concentration of urine?



Loop of Henle - ANS where is urea secreted?



Loop of Henle - ANS what reabsorbs 1/4 of the Na, K, Cl, and HCO3 in the filtrate and a small
amount of water?



DCT (distal convoluted tubule) - ANS where is the water impermeable and is under the
influence of aldosterone?



Urine not concentrated

Decreased erythropoietin, decreasing RBC's

Excess K not secreted

Toxin buildup leading to destruction of blood cells
