Question 1.
(T/F) In the kidneys, the countercurrent mechanism involves the interaction between the
flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the
countercurrent multiplier) and the flow of blood through the limbs of adjacent blood
vessels (the countercurrent exchanger). This relationship establishes and maintains an
osmotic gradient extending from the cortex through the depths of the medulla that
allows the kidneys to vary urine concentration dramatically.
Correct Answer: True
Question 2.
(T/F) The Ureter transports urine from the kidneys to the urinary bladder.
Correct Answer: True
Question 3.
(T/F) Water reabsorption through the proximal convoluted tubule is termed obligatory
water reabsorption, whereas water reabsorption through the distal convoluted tubule is
termed facultative water reabsorption.
Correct Answer: True
Question 4.
(T/F) The position of the kidneys behind the peritoneal lining of the abdominal cavity is
described by the term retroperitoneal.
Correct Answer: True
‣ (T/F) The entire responsibility for urine formation lies with the nephron.
-✓✓True
Question 5.
(T/F) Urine is 95% water by volume.
Correct Answer: True
Question 6.
(T/F) The act of emptying the bladder is called voiding.
Correct Answer: True
, Question 7.
(T/F) Glomerular filtration is an ATP-driven process.
Correct Answer: False - Glomerular filtration is a passive process
Question 8.
(T/F) In the absence of hormones, the distal tubule and collecting ducts are relatively
impermeable to water.
Correct Answer: True
Question 9.
(T/F) The collecting duct is impermeable to water in the presence of ADH
Correct Answer: False - The collecting duct is permeable to water in the
presence of ADH
Question 10.
(T/F) The urethra contains an internal sphincter of smooth muscle.
Correct Answer: True
Question 11.
(T/F) Angiotensin II is a substance made by the body to lower blood pressure during
stress.
Correct Answer: False- Angiotensin II is a substance made by the body to raise
the blood pressure
‣ (T/F) Aldosterone is a hormone that causes the renal tubules to reclaim
sodium ions from the filtrate. -✓✓True
Question 12.
(T/F) Blood pressure in the renal glomerulus is lower than in most parts of the body in
order to conserve body water.
Correct Answer: False- Blood pressure in the renal glomerulus is higher than
in most parts of the body in order to conserve body water.
Question 13.
(T/F) The proximal convoluted tubule is the portion of the nephron that attaches to the
collecting duct.
Correct Answer: False- The distal convoluted tubule is the portion of the
nephron that attaches to the collecting duct.
