Where are the kidneys located?
Posterior thoracic cavity
Anterior abdominal cavity
Posterior abdominal cavity
Inferior pelvic cavity
Inferior abdominal cavity - Answer: Posterior abdominal cavity.
Which body fluid is filtered by the kidneys?
Bile
Blood
Cerebrospinal fluid
Saliva
Feces - Answer: Blood
,Each of these organs is a component of the urinary system,
except the
kidney
urinary bladder
rectum
ureter
urethra - Answer: rectum
Determine if the statement is describing the ureter or the
urethra.
Carries urine between the kidney and the bladder: urethra or
ureter
Carries urine between the bladder and the environment: urethra
or ureter - Answer: Carries urine between the kidney and the
bladder: Ureter
Carries urine between the bladder and the environment:
Urethra
The ureter and urethra are two structures that are commonly
confused due to their similarity in spelling. The ureters are
paired muscular tubes that will carry urine from the kidney to
the bladder. The urethra is a single tube that will carry urine out
,of the bladder towards the environment.
Which hormones are secreted by the kidneys? Select all that
apply.
Renin
Erythropoietin
Calcitriol
Aldosterone
Angiotensin II - Answer: Renin
Erythropoietin
Calcitriol
Aldosterone is secreted by the suprarenal (adrenal) glands.
Angiotensin II is a blood pressure-regulating hormone that
requires activation of angiotensinogen by renin and angiotensin-
converting enzymes.
The renal veins drain into the
renal arteries
inferior vena cava
, segmental arteries
superior vena cava
abdominal aorta - Answer: Inferior vena cava
Veins do not drain into the arteries but rather into other veins
until the blood reaches the heart. The superior vena cava drains
structures from above the heart whereas the kidneys are found
in the abdominal cavity.
Which component of the kidney is responsible for the filtration
of blood plasma?
Nephron tubule
Nephron loop
Renal capsule
Collecting duct
Renal corpuscle - Answer: Renal corpuscle
The renal corpuscle consists of three filtration membranes: the
fenestrated endothelium of the glomerular capillaries, the basal
lamina, and the filtration slits created by the podocytes of the
glomerular capsule.
The nephron tubule, nephron loop, and collecting duct will
