Use the figures, tables, and text from chapters 26-27 in Tortora (your lab manual is a good supplement, too!!) to
correctly complete this assignment. Be as complete as possible in finding any locations and functions of
structures, since this material will surface on Exam 4.
Urine Flow Learning Exercise
The blood is filtrated first in the renal corpuscle (which consists of the glomerulus and
the glomerular capsule). From here, the filtrate is modified and eventually becomes
urine, which will be expelled from the body. In the exercise below, number the
structures according to when filtrate/urine passes through them. Some structures have
already been numbered for you.
_____ collecting duct
_____ major calyx
_____ nephron loop (loop of Henle)
_____ urethra
_____ minor calyx
__1__ filtrate pushed out of glomerulus, enters capsular space (space
within glomerular capsule)
_____ distal convoluted tubule
_____ ureter
_____ urinary bladder
_____ renal pelvis
_____ proximal convoluted tubule
NOW, make your own flowchart, and rewrite this sequence out in order - this will help
you remember the urine flow pathway!
