What is the purpose of the epithelial cells of Bowman's capsule in urine formation?
To act as a filtration membrane
To secrete substances into the Bowman's capsule lumen
To absorb substances from the Bowman's capsule lumen
To transport substances from the Bowman's capsule lumen to the renal tubule
Solution
The epithelial cells of Bowman's capsule, called podocytes, are arranged in an intricate manner so as to leave some minute spaces called filtration slits or slit pores. Blood is filtered so finely through these membranes, that almost all the constituents of the plasma except the proteins pass onto the lumen of the Bowman's capsule.
