Question 1.
Which vessels are most intimate with the nephron loop and serve as a point to collect
ions and water back into the blood?
a.) vasa recta
b.) cortical radiate veins
c.) afferent arterioles d.) efferent arterioles
Correct Answer: A (The vasa recta are intimate with the nephron loop and
serve as a point to collect ions and water back into the blood.)
Question 2.
Which vessels supply the cortical tissue of the kidney with blood?
a.) cortical radiate arteries
b.) interlobar arteries
c.) segmental arteries d.) arcuate arteries
Correct Answer: A (The cortical radiate arteries supply the cortical tissue of
the kidney with blood.)
Question 3.
Which of the following is NOT a function of the kidneys? a.) to regulate body fluid by
controlling excretion from sweat glands
b.) to maintain the proper balance between water and salts and between acids and
bases
c.) to metabolize vitamin D to its active form d.) to carry out gluconeogenesis during
prolonged fasting
Correct Answer: A (to regulate body fluid by controlling excretion from sweat
glands. The kidneys have no control over excretion at the level of sweat
glands.)
Question 4.
Which statement does NOT accurately describe the renal gross anatomy?
a.) The space where blood vessels and nerves enter the kidney is called the hilum.
b.) The kidneys have partial protection from the rib cage.
c.) The left kidney is lower in position because of crowding by the liver.
d.) The fibrous capsule prevents infections from spreading away from the kidney.
Correct Answer: C (The left kidney is lower in position because of crowding by
the liver is INcorrect because it is the RIGHT kidney that is position slightly
lower because of crowding by the liver.)
, Question 5.
The __________ collect(s) urine, which drains continuously from the papillae; the urine is
then emptied into the __________.
a.) renal pyramids; calyces
b.) calyces; renal pelvis
c.) renal pyramids; renal pelvis d.) renal pelvis; calyces
Correct Answer: B (calyces; renal pelvis. Formed urine enters into the renal
calyces and then the renal pelvis before entering the ureter.)
Question 6.
Hydronephrosis may be caused by all EXCEPT which of the following?
a.) renal ptosis
b.) kidney stones lodged in a ureter
c.) renal failure d.) tumor in a ureter
Correct Answer: C (renal failure. Renal failure is characterized by a significant
decrease in urine output due to damage to the nephron.)
Question 7.
Efferent arterioles supply blood to the glomerulus. T/F?
Correct Answer: false (the afferent arterioles supply blood to the glomerulus)
Question 8.
Name the strong transparent covering that encases the kidney.
Correct Answer: renal (fibrous) capsule
Question 9.
Where does the ureter penetrate the kidney?
Correct Answer: hilum
Question 10.
The ureter, blood vessels, and nerves penetrate the kidney on its medial surface. T/F?
Correct Answer: true
Question 11.
Where does filtration of the blood occur within the kidneys?
Correct Answer: renal cortex
• Identify the correct direction of urine flow from formation to exiting the
kidney. (using: medula, ureter, cortex, and pelvis) -✓✓cortex, medulla, pelvis,
ureter
