In the human kidney, increased blood pressure directly affects the function of the
A glomerulus B distal tubule C loop of Henle D A collecting duct |
A glomerulus
|
|
|
As filtrate is processed in the kidney to form urine, which substance in this fluid undergoes the greatest increase in concentration as it travels through the nephron?
A Urea B Glucose C Amino acids D Sodium ions |
A Urea
|
|
|
In the liver, urea is produced as a result of the breakdown of
A fats B glucose C glycogen D amino acids |
D amino acids
|
|
|
When a person drinks alcohol, the amount of urine produced increases. The physiological reason for this is that alcohol
A stimulates ADH secretion and more water is reabsorbed B stimulates ADH secretion and less water is reabsorbed C inhibits ADH secretion and more water is reabsorbed D inhibits ADH secretion and less water is reabsorbed |
D inhibits ADH secretion and less water is reabsorbed
|
|
|
The movement of fluid from blood in the glomerulus to Bowman's capsule is called
A filtration B diffusion C reabsorption D active transport |
A filtration
|
|
|
Which structure transports urine from the kidney to the urinary
bladder? A Ureter B Urethra C Loop of Henle D Collecting duct |
A Ureter
|
|
|
Which function is not carried out by human kidneys?
A The regulation of the pH of the blood B The formation of urea from excess amino acids C The removal of metabolic wastes from the blood D The regulation of the amount of water in the blood |
B The formation of urea from excess amino acids
|
|
|
Specialized cells in the hypothalamus called osmoreceptors monitor
the concentration of water in the blood and control the release of ADH. The event most likely to cause osmoreceptors to initiate the release of ADH is A depletion of blood glucose B dehydration of the tissues C storage of urine in the bladder D accumulation of water in the tissues |
B dehydration of the tissues
|
|
|
A molecule of urea passes through which sequence of
structures in the excretory system? A Glomerulus, Bowman's capsule, loop of Henle, collecting duct, ureter, bladder, urethra B Bowman's capsule, glomerulus, loop of Henle, collecting duct, ureter, bladder, urethra C Bowman's capsule, glomerulus, loop of Henle, ureter, collecting duct, bladder, urethra D Glomerulus, Bowman's capsule, loop of Henle, collecting duct, urethra, bladder, ureter |
A Glomerulus, Bowman's capsule, loop of Henle, collecting duct,
ureter, bladder, urethra |
|
|
In urine, the absence of large protein molecules is due to their
inability to pass into A collecting ducts B Bowman's capsules C the urinary bladder D proximal convoluted tubules |
B Bowman's capsules
|
|
|
Blood leaving a kidney has lost much of its
A urea B plasma C glucose D vitamins |
A urea
|
|
|
The normal sequence of processes in urine formation is
A filtration, reabsorption, tubular secretion B reabsorption, filtration, tubular secretion C tubular secretion, filtration, reabsorption D tubular secretion, reabsorption, filtration |
A filtration, reabsorption, tubular secretion
|
|
|
A human blood sample contains a greater concentration of urea than
normal. This may have been caused by the person having eaten excessive amounts of A fat B sugar C starch D protein |
D protein
|

|
|
|
Most of the nutrients are reabsorbed from tubular urine in the region
of the: A distal tubule B loop of Henle C collecting ducts D proximal tubule |
D proximal tubule
|
|
|
Which of the following processes is responsible for the increased
pressure in the glomerulus? A dilation of the aorta and constriction of the vena cava B dilation of the renal artery and constriction of the renal vein C dilation of the efferent arteriole and constriction of the afferent arteriole D dilation of the afferent arteriole and constriction of the efferent arteriole |
D dilation of the afferent arteriole and constriction of the efferent
arteriole |
