Which of the following is NOT a function of the kidneys?
Exchange of oxygen and carbon dioxide with the tissues
Which of the following should NOT be found in the filtrate in the Bowman’s capsule?
White blood cells
Which structures form the filtration membrane in the nephron?
Glomerulus and the glomerular capsule
Which of the following resulted in an increase in glomerular filtration rate?
Decreasing the efferent arteriole diameter and increasing the afferent arteriole diameter
Which of the following resulted in a decrease in glomerular capillary pressure?
Increasing the efferent arteriole diameter and decreasing the afferent arteriole diameter
Which is the normal range for glomerular filtration rate?
80-140 mL/min
What is(are) the driving force(s) for filtration in the nephron?
Hydrostatic pressure gradients and osmotic pressure gradients
The functions of the nephron include all of the following EXCEPT:
Glomerular secretion
In this activity, we will explore the effect of _____.
Blood pressure on glomerular filtration rate
What is the name for the “ball” of capillaries found in the renal corpuscle?
Glomerulus
As the pressure in the beaker increased, which of the following occurred?
Glomerular filtrate rate increased, and urine volume increased
The pressure in the left source beaker simulates _____.
Blood pressure
With the valve between the collecting duct and urinary bladder closed, _____.
Urine volume was zero
With the valve between the collecting duct and the urinary bladder closed and with the pressure increased, ______.
The glomerular filtration rate increased and the glomerular pressure increased
Altering the radii of the afferent and efferent arterioles provides for
Glomerular filtration rate homeostasis and glomerular hydrostatic pressure homeostasis
Because the alteration of the afferent or efferent arteriole occurs within the nephron, we refer to this mechanism as _____.
Intrinsic
Which of the following would decrease glomerular filtration rate?
Increasing the efferent arteriole radius and/or decreasing the afferent arteriole radius
In this activity, the drain beaker (second beaker in the flow) simulates the _____.
Renal vein
When the beaker pressure was lowered, which of the following decreased?
Glomerular pressure, glomerular filtration rate and urine volume
When beaker pressure was lowered, which of the following decreased?
Glomerular pressure, glomerular filtration rate and urine volume
When blood pressure increases, what changes can occur to maintain glomerular filtration rate?
Constriction of the afferent arteriole and dilation of the efferent arteriole
When the efferent arteriole constricts, ______.
The back pressure in the Bowman’s capsule increases
Interstitial fluid is located in the _____.
Spaces surrounding the kidney tubule
Secretion of ADH would _______.
Decrease urine output
The reabsorption of water and solutes _____.
Is passive, depends on concentration gradients and is into the peritubular capillaries
When ADH is present in the filtrate, _______.
Urine concentration increases
What happened to the urine volume when the solute gradient in the interstitial space was increased?
The urine concentration increased
What will happen to the urine volume if ADH is NOT added to the collecting duct?
The urine volume will increase
