They areemptied from the mouths of the uriniferous tubules, at theapices of these pyramids, into the pelvis of the kidneys,and from here the urine passes through the ureters intothe bladder and is voided through the urethra. From these tortuous uriniferous tubules the tube-castsare formed. They are cylindric in shape and usuallycomposed of the lining epithelium in various stages of 234 DISEASES OF THE URINARY TRACT 235 degeneration.
