ascending limb reabsorbs K+

Answer 6

True

Question 7

In loop of Henle:

descending limb impermeable to water

Answer 7

False

Question 8

In loop of Henle:

Na+ reabsorption is required for uptake of glucose

Answer 8

False

Question 9

In loop of Henle:

Cells of descending limb have few microvilli

Answer 9

True

Question 10

In loop of Henle:

cells of ascending limb have many mitochondria

Answer 10

True

Question 11

Regarding sodium balance and regulation:

body sodium levels are used to regulate osmolarity

Answer 11

False
It’s water
Sodium used to regulate fluid volume

Question 12

Regarding sodium balance and regulation:

under normal conditions increased GFR leads to increased Na reabsorption

Answer 12

True

More fluid into tubular system

Question 13

Regarding sodium balance and regulation:

Blocking Na/Cl transporter in DCT increases plasma Ca2+

Answer 13

True

Question 14

Regarding sodium balance and regulation:

diuretics that inhibit aldosterone increase K+ secretion by increasing flow

Answer 14

False
Supress it
bc are potassium sparing diuretics

Question 15

Regarding sodium balance and regulation:

Reduced Na in the DCT leads to renin secretion

Answer 15

True
