The urinary system does all of the following except
a. secretes excess glucose molecules b. regulates blood volume c. contributes to stabilizing blood pH d. eliminates organic waste products |
a. secretes excess glucose molecules
|
|
|
Urine is produced by the
|
kidneys
|
|
|
Urine is carried to the urinary bladder by
|
the ureters
|
|
|
All of the following are true about the kidneys except that they are
a. located in a position that is retroperitoneal b. surrounded by a renal capsule c. located within the peritoneal cavity d. surrounded by a thick layer of adipose tissue |
c. located within the peritoneal cavity
|
|
|
The outermost layer of kidney tissue is the
|
renal cortex
|
|
|
The conical shaped structures that are located in the renal medulla are called
|
pyramids
|
|
|
Bowman's capsule and the glomerulus make up the
|
renal corpuscle
|
|
|
The region known as the macula densa is part of
|
the distal convoluted tubule
|
|
|
The cells of the macula densa and the juxtaglomerular cells form the
|
juxtagulomerular apparatus
|
|
|
The basic functional unit of the kidney is the
|
nephron
|
|
|
The glomerulus is
|
a knot of capallaries that lies within the renal corpuscle
|
|
|
The process of urine formation involves all of the following except
a. filtration of the plasma b. reabsorption of water c. secretion of wastes d. secretion of excess lipoprotein and glucose molecules |
d. secretion of excess lipoprotein and glucose molecules
|
|
|
The process of filtration occurs at
|
Bowman's capsule
|
|
|
Each of the following is a normal constituent of urine except
a. hydrogen ions b. urea c. salts d. glucose |
glucose
|
|
|
The glomerular filtration rate is regulated by all of the following except
a. autoregulation b. sympathetic neural control c. hormonal regulation d. parasympathetic control |
d. parasympathetic control
|
|
|
Sympathetic stimulation of the kidney can accomplish all of the following, except
a. produce powerful vasoconstriction of the afferent arterioles b. increase the glomerular filtration rate c. result in the release of renin d. produce renal ischemia |
b. increase the glomerular filtration rate
|
|
|
The process of filtration is driven by
|
blood hydrostatic pressure
|
|
|
The ability to form a concentrated urine depends on the functions of
|
the loop of Henley
|
|
|
The area of the nephron where the greatest reabsorbance of of ions, water, and nutrients takes place is the
a. Bowman's Capsule b. dollecting duct c. loop of Henle d. proximal convoluted tubule |
proximal convoluted tubule
|
|
|
When the level of ADH increases
|
less urine is produced
|
|
|
In response to increased levels of aldosterone, the kidneys produce
|
urine with a lower concentration of sodium ions
|
|
|
The ureters and urinary bladder are lined by ________ epithelium.
|
transitional
|
|
|
During the micturation reflex
|
there is increased activity of the parasympathetic motor neurons that control the smooth muscle of the bladder
|
|
|
When the renal threshold for a substance exceeds its tubular maximum
|
the amount that exceeds the tubular maximum will be found in the urine
|
|
|
In the loop of Henle
|
sodium and chloride ions are actively transported out of the ascending limb
|
|
|
Urea is:
|
passively reabsorbed in the proximal convoluted tubule
|
|
|
ADH:
|
increases the permeability of the collecting ducts to water
|
|
|
In response to excess water in the body:
|
the permeability of the distal convoluted tubules and collecting ducts to water is decreased
|
|
|
Each of the following organs is part of the urinary system except
|
liver
|
|
|
The expanded proximal end of the ureter forms the
|
renal pelvis
|
