BIOD 152 Module 7 Problem Set Questions & Answers 2026
| High-Yield Review | Graded A+
1. The filtrate leaving the Loop of Henle is:
hypertonic
hypotonic
2. Describe the significance of the renal pyramids in the structure of the
kidneys.
The renal pyramids are the primary site for acid-base balance.
The renal pyramids are essential for urine formation and contain the
collecting ducts that transport urine to the renal pelvis.
The renal pyramids are involved in blood filtration and detoxification.
The renal pyramids are responsible for regulating blood pressure in
the kidneys.
3. If a patient has impaired function of the peritubular capillaries, what aspect of
kidney function might be affected?
Secretion of waste products
Filtration of blood
Reabsorption of water and solutes
Formation of urine
4. Describe how changes in blood pressure detected by baroreceptors can
affect the function of nephrons.
Baroreceptors have no effect on nephron function.
, Changes in blood pressure detected by baroreceptors can lead to
adjustments in renal blood flow, affecting glomerular filtration rate
and urine production.
Baroreceptors increase urine concentration regardless of blood
pressure.
Baroreceptors only influence the bladder, not the kidneys.
5. A normal characteristic of urine is:
a strong odor
a dark yellow color
light yellow color
a thick, mucous like consistency
6. If a patient experiences a significant drop in systemic blood pressure, how
might autoregulation in the kidneys respond?
It would decrease filtration rate.
It would shut down renal function.
It would attempt to maintain renal blood flow.
It would increase urine production.
7. If a patient experiences a significant drop in blood pressure, how might this
affect their nephron function and urine output?
Nephron function may decrease, leading to reduced urine output.
Nephron function will increase, causing excessive urine output.
Nephron function will remain unchanged, and urine output will
increase.
, Nephron function will be unaffected, but urine will become more
concentrated.
8. Describe the role of nephrons in the urinary system.
Nephrons store urine until excretion.
Nephrons are responsible for filtering blood and forming urine.
Nephrons transport urine to the bladder.
Nephrons regulate blood pressure.
9. Describe how autoregulation affects renal blood flow in the kidneys.
Autoregulation increases renal blood flow during high blood pressure
only.
Autoregulation decreases renal blood flow when blood pressure is
low.
Autoregulation is solely dependent on hormonal signals.
Autoregulation maintains a relatively constant renal blood flow
despite changes in systemic blood pressure.
10. Describe how the loop of Henle contributes to the overall function of the
nephron.
The loop of Henle filters blood to remove waste products.
The loop of Henle creates a concentration gradient that allows for
the reabsorption of water and salts, aiding in urine concentration.
The loop of Henle transports urine to the bladder.
The loop of Henle absorbs nutrients from the blood.
11. What are the three layers of the bladder called?
, Inner, middle, and outer layers
Epithelial, connective, and muscular
Mucosa, muscularis, and adventitia
Serosa, submucosa, and muscularis
12. Describe how hormones influence renal blood flow and its significance in
kidney function.
Hormones only affect urine concentration and have no impact on
blood flow.
Hormones primarily influence the bladder's ability to store urine.
Hormones are not involved in renal blood flow regulation.
Hormones such as renin and aldosterone regulate renal blood flow
by affecting blood pressure and sodium reabsorption.
13. If a patient has a blood hydrostatic pressure of 70 mmHg, a colloid osmotic
pressure of 30 mmHg, and a capsular pressure of 20 mmHg, what is the net
filtration pressure, and what does this indicate about kidney function?
Net filtration pressure is 30 mmHg, indicating excessive filtration.
Net filtration pressure is 40 mmHg, indicating kidney failure.
Net filtration pressure is 10 mmHg, indicating reduced filtration.
Net filtration pressure is 20 mmHg, indicating that filtration is
occurring normally.
14. What is the primary role of the distal convoluted tubule in the nephron?
Regulation of blood pressure.
Filtration of blood plasma.
