Which of the following is not a normal constituent of urine
Nitrogenous wastes
Hormones
Pigments
Blood cells
This hormone tends to decrease the amount or urine produced.
a. ANH
b. Aldosterone
c. ADH
d. Both B and C
Which of the following is/are classified as an accessory organ of the urinary system
Ureters
Urinary bladder
Urethra
All of the above
The function of the urinary bladder is to
a. serve as a reservoir for urine before it leaves the body.
b. expel urine from the body, aided by the urethra.
c. help concentrate the urine in periods of dehydration.
d. Both A and B
The nitrogenous wastes in the urine are usually the result of protein catabolism. They include all but:
urea
ammonia
creatinine
amino acids
Reabsorption, as performed in the kidney, may be defined as the
movement of molecules out of the tubule and into the peritubular blood
movement of molecules out of the peritubular blood and into the tubule for excretion
movement of water and solutes from the plasma in the glomerulus, across the glomerular-capsular membrane, and into the capsular space of Bowman’s capsule
volume of plasma from which a substance is removed by the kidney per minute
This hormone tends to increase the amount of urine produced
Of all the blood pumped per minute by the heart, approximately One-fifth One-third One-half Three-fourths( One-fifth, One-third, One-half, Three-fourths ) goes through the kidneys.
ADH has the greatest effect on the reabsorption of water in the
proximal tubule
ascending loop of Henle
descending loop of Henle
distal tubule
This vein drains into the renal vein
Lobar vein
Arcuate vein
Interlobular vein
Segmental vein
The calyces of the kidney join together to form a large collection reservoir called the
renal columns
renal pyramids
renal pelvis
hilum
A good description of the urinary system is that it
produces urine
balances blood plasma
maintains the dynamic consistency of the internal fluid environment
does all of the above
This is the first branch of the segmental artery
Afferent arterioles
Lobar arteries
Arcuate arteries
In the average bladder, this amount of urine causes a moderately distended sensation and the desire to void
250 ml
100 ml
600 ml
150 ml
Urine formation involves all the following processes except
filtration
catabolism
reabsorption
secretion
In the kidney, blood flows from the interlobular artery into the
glomerulus
efferent arteriole
afferent arteriole
peritubular capillaries
Which following structure does not enter or leave through the hilum of the kidney?
Calyx
Renal artery
Renal vein
Ureter
A drop in systemic blood pressure would cause the filtration rate to
increase
decrease
stay the same
all of these
Under normal conditions, most nutrients are reabsorbed in which portion of the nephron?
Proximal tubule
Ascending loop of Henle
Distal tubule
Collecting tubule
Which of the following is not normally secreted into the distal or collecting tubules?
Potassium ions
Hydrogen ions
Ammonium ions
Sodium ions
The movement of molecules out of the tubules and into the peritubular blood defines
glomerular filtration
micturition
