Practice Quiz
I. Trace the Blood Flow Through a Kidney:
I am an RBC in the Descending Abdominal Aorta traveling to the distal-most part of the descending
Limb of the Loop of Henle of one Nephron in the Right Kidney to off-load my cargo of O2, and then
make my way to the Right Atrium of the Heart. Please indicate my route by correctly sequencing the
following structures in numerical order. It is started and finished off for you, but you must fill in
everything in between. Place an “X” on the blank for any structure that I will NOT utilize on my trip.
__1__Desc. Abdominal Aorta
_____Interlobar Artery
_____ Right Renal Artery
_____Interlobar Vein
_____Segmental Vein
_____ Interlobular Vein
_____Interlobular Artery
_____Peritubular capillaries
_____ Vasa recta
_____Efferent arteriole
_____ Right Renal Vein
_____ Arcuate Artery
_____Segmental Artery
_____Afferent arteriole
_____ Glomerulus
_____Arcuate Vein
_____Inferior Vena Cava
__17__Right Atrium of Heart
II. Circle T (True) or F (False). If the statement is false, cross out the word(s) that make it false
and write in an appropriate correction so that the statement now becomes a true statement.
T F 18. During stressful situations, urinary output is likely to decrease, partly due to an increase in
sympathetic nerve impulses leading to vasoconstriction of renal blood vessels.
T F 19. ADH increases permeability of parts of the distal convoluted tubule and the collecting ducts by
inserting aquaporins into the wall of these sections of the tubules.
T F 20. Blood in glomerular capillaries flows into arterioles, not into venules.
T F 21. A person taking a diuretic is likely to urinate less than a person taking no medications.
T F 22. An efferent arteriole normally has a larger diameter than an afferent arteriole.
T F 23. Renal clearance of a substance is equal to the amount of that substance filtered plus the amount
reabsorbed minus the amount secreted.
III. Arrange the answers in correct sequence:
___, ___, ___, ___, ___ 24. Pathway of glomerular filtrate: A. Ascending limb of loop B. Collecting duct
C. Descending limb of loop D. Distal convoluted tubule E. Proximal convoluted tubule
____, ____, ____, ____ 25. From most superficial to deepest: A. Renal capsule
C. Renal cortex
B. Renal medulla
D. Renal pelvis

mechanisms of GFR (Glomerular Filtration Rate) in order of most localized to
most widespread:
A. Hormonal regulation B. Renal autoregulation C. Neural regulation
IV. Using the blanks provided, fill in the word or phrase that best fits the description given:
__________________28. This is the part of a nephron where most H2O reabsorption takes place.
__________________29. This is the collective name of a glomerulus and its glomerular capsule.
__________________30. These are the two components of a nephron.
__________________
__________________31. This is the term for excessive urine production; and its opposite of
__________________
less than 50 ml of urine production per day.
__________________32. This is the “average” quantity of urine produced per day.
V. Circle T (True) or F (False). If the statement is false, cross out the word(s) that make it false and
write in an appropriate correction so that the statement now becomes a true statement.
