Please help me with these questions - more than one answer may be correct for each one: 1) Which of the following is involved in GFR regulation? A) Sympathetic NS control B) Changes to capillary Kf C) Contraction/relaxation of podocytes D) The juxtaglomerular apparatus E) Capillary blood pressure 2) Hyperventilating would cause A) blood oxygen to rise proportionally less than carbon dioxide to lower B) urine to become more basic if continued for an extended time period (hours/days) C) blood oxygen to rise proportionally more than carbon dioxide to lower D) blood pH to rise E) blood pH to decrease 3) At this moment I am drinking a hot cup of coffee. It will likely make me need to visit the restroom before I am finished writing this test. Why does coffee increase urination more than other non-caffeinated beverages?
Please help me with these questions - more than one answer may be correct for each one:
1) Which of the following is involved in GFR regulation?
A)
Sympathetic NS control
B)
Changes to capillary Kf
C)
Contraction/relaxation of podocytes
D)
The juxtaglomerular apparatus
E)
Capillary blood pressure
2) Hyperventilating would cause
A)
blood oxygen to rise proportionally less than carbon dioxide to lower
B)
urine to become more basic if continued for an extended time period (hours/days)
C)
blood oxygen to rise proportionally more than carbon dioxide to lower
D)
blood pH to rise
E)
blood pH to decrease
3) At this moment I am drinking a hot cup of coffee. It will likely make me need to visit the restroom before I am finished writing this test. Why does coffee increase urination more than other non-caffeinated beverages?
A)
caffeine blocks adenosine receptors in the juxtaglomerular apparatus
B)
caffeine cases vasoconstriction
C)
caffeine stimulates your CNS, causing you to need to pee quicker after consuming coffee, but you are not actually producing more urine.
D)
caffeine causes constriction of the podocytes, which increases GFR
E)
caffeine decreases blood pressure which increases GFR
