1

Which organ system does not excrete waste?

1

Which is not a function of the kidneys?

1

Which of the following is not an organ of the urinary system?

1

A patient enters a hospital after a motorcycle accident. He complains of midback pain. X rays reveal both rib and pelvic fractures. His emergency room examination includes urinalysis. Which of the following findings from the urinalysis would most likely suggest trauma to the kidneys from the accident, but not to the urinary bladder?

1

The innermost connective tissue layer protecting the kidney and assisting in staving off infection is known as

1

A single lobe of a kidney is comprised of

1

A renal pyramid voids urine into

1

Which of these correctly traces blood flow from the renal artery into the renal cortex?

1

The transition from an afferent arteriole to an efferent arteriole occurs in the:

1

The average person has approximately __________ nephrons per kidney

1

Which of these correctly traces blood flow from the renal cortex to the renal vein?

1

Blood plasma is filtered in

1

Which of these form the inner layer of the glomerular capsule and wrap around the capillaries of the glomerulus?

1

All of the following are composed of cuboidal epithelium with the exception of

1

Which are primarily responsible for maintain the salinity gradient of the renal medulla?

1

In the nephron, the fluid that immediately precedes urine is known as

1

Renin hydrolyzes angiotensinogen released from the _______ to form angiotensin I

1

Because of the great deal of active transport that occurs here, the _______ of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption

1

Proximal convoluted tubules are responsible for reabsorbing all of the following except:

1

Atrial natriuretic peptide reduces blood volume and pressure by all of the following means except

1

Hypocalcemia stimulates

1

Which renal structure is responsible for producing hypertonic urine by reabsorbing water while allowing metabolic wastes and NaCl to pass through?

1

The urine is most likely to be hypotonic when

1

Which of the following does not contribute to water conservation?

1

The countercurrent multiplier recaptures and is based on fluid flowing in _ direction in two adjacent tubules

1

The overall purpose of the countercurrent exchange system is

1

Which of these induces renin secretion, constricts afferent arterioles, and reduces GFR and urine volume?

1

Normal urine from a healthy person can be expected to contain all of the following except:

1

What is the term for the pigment responsible for the color of urine?

1

The minimum daily output of urine to meet the definition of polyuria is:

1

Prior to chemical tests for glycosuria, clinicians checked for sweetness of the urine as a sign of:

1

Loop diuretics reduce body water context by acting on:

1

A hospital patient produces 4 mL. min of urine with a urea concentration of 8mg/mL. Venous blood draw reveals urea concentration of .4 mg/mL. What is the percentage of cleared urea from glomerular filrate?

1

Which two substances are most useful for determining a patient's glomerular filtration rate?

1

Creatinine has a renal clearance of 140 mL/min due to the fact that:

1

Which of the following is not found in the ureter?

1

Which muscle is located in the bladder?

1

Which is not a portion of the urethra?

1

Micturition is another term for:

1

The ureters pass anterior to the bladder and enter it from below

1

Albuminuria is a common sign of diabetes mellitus

1

Diseases that affect the descending corticospinal tracts may limit inhibition of the sacral somatic motor neurons and thus could result in urinary incontinence

1

Ethyl (drinking) alcohol stimulates the secretion of ADH, thereby reducing reabsorption by the collecting duct

1

Parathyroid hormone increases phosphate excretion by the proximal convoluted tubule as well as promotes synthesis of calcitriol

1

The countercurrent multiplier mechanism for water conservation was discovered by limiting studies to humans and thus hypothesizing how form determines function

1

The thick segment of the nephron loop is impermeable to water

1

Glomerular filtration occurs because glomerular oncotic pressure overrides glomerular blood pressure

1

Angiotensin converting enzyme is found only in the kidneys and converts angiotensinogen to angiotensin I

1

Cells in the cleft between the afferent and efferent arterioles and among capillaries of the glomerulus are known as mesangial cells

1

Glomerular capillaries suffer little damage from hypertension because of the protective influence of the afferent arterioles
