1.
Which statement about the location of the kidneys is correct?
a)
The kidneys lie underneath the 10th rib.
b)
The kidneys lie anterior to the parietal peritoneum.
c)
The kidneys lie against the anterior abdominal wall.
d)
The location can be described as retroperitoneal.
2.
What is the filtration unit of the kidney?
a)
Glomerulus
b)
Nephron
c)
Renal pelvis
d)
Renal papilla
3.
What is the purpose of the adipose tissue surrounding the kidneys?
a)
It keeps the kidneys warm.
b)
It provides the kidneys with fuel.
c)
It holds the kidneys in place.
d)
It protects the kidneys.
4.
Which of the following statements accurately describes the function of Bowman’s capsule?
a)
Bowman’s capsule captures fluid leaking out of the glomerulus and returns it to the peritubular capillaries.
b)
Fluid that filters out of the glomerulus collects in between the two layers of Bowman’s capsule and then flows into the renal tubule on the other side of the capsule.
c)
Bowman’s capsule applies pressure to the glomerulus to increase the speed of filtration.
d)
Bowman’s capsule applies pressure to the glomerulus to decrease the speed of filtration.
5.
What is the renal tubule?
a)
A mass of capillaries that makes up the glomerulus
b)
Branches of the renal artery that supplies blood to the renal cortex
c)
A collection of tubelike structures that leads away from the glomerulus
d)
Tubelike structures that converge to form the ureter
6.
What substance is filtered by the kidney?
a)
Urine
b)
Intracellular fluid
c)
Blood
d)
Tissue fluid
7.
What factor drives filtration in the glomerulus?
a)
Energy from ATP
b)
Energy from glucose
c)
Diffusion
d)
A pressure gradient
8.
What is the most likely cause of protein in urine?
a)
High pressure within the glomerulus
b)
Damaged glomerular capillaries
c)
High-protein diet
d)
Protein is a normal finding in urine
9.
Which structural characteristic of the proximal convoluted tubule enhances its role in tubular reabsorption?
a)
Juxtaglomerular cells
b)
Microvilli
c)
Microscopic pores
d)
Cilia
10.
How much of the fluid filtered by both kidneys is reabsorbed by the body?
a)
5 percent
b)
80 percent
c)
99 percent
d)
30 percent
11.
How does high blood pressure damage kidneys?
a)
High blood pressure drives filtrate formation at an accelerated rate, which wears out the glomerulus.
b)
The kidneys must work against high blood pressures to excrete filtrate, which places a strain on the glomerulus.
c)
High blood pressure damages the endothelium of glomerular capillaries.
d)
High blood pressure increases pressure within the glomerulus, causing glomerular capillaries to burst.
12.
Which of the following is not normally found in urine?
a)
Ammonia
b)
Glucose
c)
Uric acid
d)
Sodium
13.
Each nephron contains a cluster of capillaries called a
a)
Trigone
b)
Glomerulous
c)
Bowman's capsule
d)
Loop of Henle
14.
A urine output of less than 400ml/day is called:
a)
Oliguria
b)
Protienuria
c)
Tachyuria
d)
Bradyuria
15.
The renin-angiotensin-aldosterone system is a key mechanism of what?
a)
Maintaing acid-base balance (pH) in the blood.
b)
Maintaining homeostasis by regulating heart rate in an acceptable range.
c)
Maintaining blood pressure and, therefore, a steady glomerular filtration rate
d)
Maintaing steady rate of peristalsis in the GI tract.
