Which of the following structures are the filtration slits related to?
Pedicles
Which of the following structures participates in the concentration of medullary interstitium and urine?

Why would a patient with chronic renal failure develop anemia?
Because the kidney produces erythropoietin
What would sympathetic stimulation of the kidney result in?
Renin release from the granular cells
Why would the renal blood flow decrease when the renal venous resistance increases?
