Random bits and bobs

Question 1

What happens to the GFR if the ureters are obstructed?

Answer 1

Decreases

• Feedback system decreases pressure in Bowman’s Capsule
• Will cause the hydrostatic pressure to decrease which will filtration rate

Question 2

What happens to the reabsorption of potassium in acidic conditions

Answer 2

The buffering of H+ will lead to the movement of K+ out of cells and therefore and increase in the plasma

Question 3

Are ACE enzyme vasodilators or vasoconstrictors

Answer 3

Vasodilators

Question 4

Would GFR decrease in response to a change in renal arterial BP?

Answer 4

NO- it is independent of BP due to autiregulation

Question 5

Would Increase in sodium intake lead to an increase or decrease in renin?

Answer 5

Increase in sodium would lead to an increase in BP and therefore a decrease in renin

Question 6

What happens to GFR during hypoprotenemia?

Answer 6

Reduced plasma proteins in the blood
decreased oncotic pressure
increased filtration

Question 7

Does an increase in Sodium increase or decreased ICF/ ECF

Answer 7

increases ECF
Decreased ICF

And therefore leads to a decrease in hematocrit
