multiple choice questions

Question 1

True of false
the renal cortex and renal medulla are parts of the kidneys where nephrons are found

Answer 1

true

Question 2

Which of the statements about the urinary system is correct?
a) urea is produced by the kidneys
b) erythropoietin (EPO) is released in response to low blood pressure
c) the ureter allows urine to be excreted outside the body
d) in urine formation, water enters or exits the renal corpuscle and renal tubule using active transport
e) alcohol increases urine output by inhibiting the release of ADH

Answer 2

e) alcohol increases urine output by inhibiting the release of ADH
because
With Alcohol (inhibiting ADH): Alcohol inhibits the release of ADH, so the kidneys don’t reabsorb as much water, leading to larger volumes of dilute urine and increased urine output.

Question 3

true or false?
the renal pelvis collects urine produced by the nephrons and sends it to the ureters

Answer 3

true

Question 4

which statement is incorrect regarding the maintenance of homeostasis?
a) Bicarbonate iosn (HCO3-) reabsorption and H+ secretion together help balancing blood pH
b) Combined, the sctions triggered by angiotensin II increase blood volume and bring blood pressure back to normal
c) In osmoregulation, ADH promotes water filtration and production of hypertonic urine
d) Erythropoietin produced by the kidneys stimulates the bone marrow to produce RBC

Answer 4

c) In osmoregulation, ADH promotes water filtration and production of hypertonic urine

it favors water REABSORPTION not water filtration

Question 5

Among the following vessels, which ones directly participate in reabsorption and secretion?
a) afferent arterioles
b) renal veins
c) petibular capillaries
d) efferent arterioles
e) glomerular capillaries

Answer 5

c) petibular capillaries

Question 6

True or false?
Secretion of bicarbonate ions (HCO3-) is necessary to increase blood pH

Answer 6

FALSE
REABSORPTION of bicarbonate ions will cause an increase in blood pH

Question 7

The duct that delivers urine our of the body is the:
a) ureter
b) urethra
c) renal artery

Answer 7

b) urethra

Question 8

what is the name of the microscopic urine-forming units of the kidneys?

Answer 8

nephron

Question 9

which urine-forming process is described as ‘’ the primary removal of elements from blood?’’

Answer 9

filtration

Question 10

true or false:
it is completely normal to detect red blood cells (RBC) in a urine sample?

Answer 10

false

Question 11

which urine-forming process is described as ‘’ returning elements from filtrate to blood?’’

Answer 11

reabsorption

Question 12

which urine-forming process is described as ‘’ removal of elements from blood to filtrate (2nd attempt) ?’’

Answer 12

secretion
