This is the site of the final concentration of urine:
Loop of Henle
Distal Convoluted Tubule
Collecting Tubule
Bladder
This term describes the limit to how much an analyte will be completely reabsorbed from the filtrate:
acid-base balance
ultrafiltrate
osmotic gradient
renal threshold
Functional unit of the kidney
Bowman's Capsule
glomerulus
nephron
bladder
This type of reabsorption requires expenditure of energy and attached to a carrier protein:
active
non-existent
passive
spontaneous
virtual
This eliminates the urine from the bladder to the outside of the body
bladder
kidney
urethra
ureter
This repels molecules with a negative charge even though they are small enough to pass through:
Bowman's Capsule
glomerulus
podocytes
shield of negativity
The hydrostatic pressure present is the glomerulus results from:
the smaller afferent arteriole and larger efferent arteriole
the blood pressure of the indiviual
larger afferent arteriole and smaller efferent arteriole
cardiac output
This test is used to measure the filtering capacity of the glomeruli:
osmolality
titratable acidity
creatinine clearance
PAH
This test is useful in measuring the viability of a transplanted kidney:
freezing-point osmometry
cystatin C
free water clearance
Beta2-microglobulin
Which of the following contributes to specific gravity, but not to osmolality?
chloride
salt
urea
glucose
Which statement regarding urea is true?
Blood urea levels are independent of diet.
Urea is 100% filtered by the glomerulus.
Urea is not significantly reabsorbed by the tubules
The urine flow rate does not affect urea.
The first layer of the filtration barrier includes:
(select all which apply)
capillary endothelial cells
fenestrations
podocytes
shield of negativity
Secretion of renin is stimulated by:
podocytes
basement membrane
vasa recta
macula densa
The ultrafiltrate leaving the glomerulus has a specific gravity of:
1.005
1.001
1.010
1.008
A 24-hour urine collection can be affected by all of the following, except:
drugs
muscle mass
improper storage
urine flow
Glucose will appear in the urine when the:
glucose blood level is >180 mg/dL
Tm for glucose is reached
renal threshold for glucose is exeeded
all the above
The type of nephron responsible for renal concentration is the:
afferent
cortical
efferent
juxtamedullary
_______ transport is the movement of molecules across a membrane as a result of differences in the concentration gradient.
active
afferent
efferent
passive
Kidneys function to regulate:
(select all which apply)
acid-base balance
form urine
maintain blood pressure
stores waste products
eGFR should not be used for which patient population:
athletes
elderly
females
pediatric
Water is reabsorbed throughout the nephron, with the exception of:
Ascending limb of the Loop of Henle
Descending limb of the Loop of Henle
These are responsible for maintaining the acid-base balance:
(select all which apply)
pulmonary system
digestive system
renal system
blood-buffer system
Which term defines lack of urine excretion?
diuresis
oliguria
nocturia
polyuria
anuria
Which term defines a decrease in urine excretion?
diuresis
oliguria
nocturia
polyuria
anuria
Which term defines excessive urine excretion (> 3 L/day)?
diuresis
oliguria
nocturia
polyuria
anuria
