Blood vessels, nerves, and the ureter enter or leave the kidney at a region called the __________.
hilum
renal sinus
renal fascia
renal medulla
Regions containing cortical tissue that are located between the pyramids are referred to as __________.
minor calyx
renal papillae
renal columns
renal corpuscles
A renal pyramid passes urine into a __________.
minor calyx
major calyx
renal medulla
renal papilla
The structural and functional units of the kidney are called __________.
nephrons
pyramids
renal papillae
renal columns
The renal corpuscle consists of
Bowman capsule and the renal pelvis.
the glomerulus and Bowman capsule.
the renal pelvis and the renal tubules.
the proximal convoluted tubule and the glomerulus.
Which of these correctly traces blood flow from the renal cortex to the renal vein?
Arcuate v. → interlobar v. → segmental v. → renal v.
Segmental v. → arcuate v. → interlobar v. → renal v.
Interlobar v. → interlobular v. → arcuate v. → renal v.
Interlobular v. → arcuate v. → interlobar v. → renal v.
The proximal convoluted tubule is
impermeable to water.
permeable to water if ADH is present.
lined with epithelial cells that lack microvilli.
the site of glucose and amino acid reabsorption.
Most water is reabsorbed from the filtrate in the __________.
distal convoluted tubule
ascending loop of Henle
descending loop of Henle
proximal convoluted tubule
Renin converts __________.
angiotensin II to angiotensin I
angiotensin I to angiotensin II
angiotensin II to angiotensin III
angiotensinogen to angiotensin I
The lining of the bladder that accommodates the expansion of this organ is composed of __________.
transitional epithelium
stratified columnar epithelium
stratified squamous epithelium
pseudostratified columnar epithelium
The __________ is responsible for contraction of the urinary bladder during micturition.
trigone
detrusor muscle
micturition muscle
internal urinary sphincter
Why is the external urinary sphincter under conscious control?
It is made of adventitia.
It is made of skeletal muscle.
It is made of smooth muscle.
It is part of the detrusor muscle.
Voluntary micturition
is a reflex action.
is common in infants.
involves higher brain centers.
involves control of the internal sphincter.
The urge to urinate results from the ____________.
micturition reflex
unmicturition reflex
voluntary urinary mechanism
involuntary urinary mechanism
Tubular load refers to the amount of a given substance that
can be secreted into the filtrate.
can be actively reabsorbed from the filtrate.
passes through the filtration membrane into the nephron each minute.
is present in the blood as it enters the afferent arteriole of the nephron.
When the tubular maximum for a substance is exceeded,
the excess goes into the blood.
the excess remains in the urine.
more of the substance is actively secreted.
more of the substance is reabsorbed.
Increased aldosterone causes increased
urine volume.
sodium secretion.
potassium secretion.
reabsorption of hydrogen ions.
Formation of filtrate depends on a __________.
volume gradient
pressure gradient
temperature gradient
concentration gradient
