Respuesta
-
0 mmol/day
-
10-20 mmol/day
-
~720 mmol/day
-
100-200 mmol/day
Pregunta 2
Pregunta
The majority of tubular reabsorption occurs in what part of the nephron?
Respuesta
-
Proximal Convoluted Tubule
-
Bowman's Capsule
-
Loop of Henle
-
Distal Convoluted Tubule
Pregunta 3
Pregunta
In the event of elevated glomerular filtration rate (GFR), the proportion of sodium reabsorbed in the proximal tubule:
Respuesta
-
Increases
-
Decreases
-
Remains constant
-
Sodium is not reabsorbed in the proximal tubule
Pregunta 4
Pregunta

Respuesta
- True
- False
Pregunta 5
Pregunta
Compared to later segments, earlier segments of the proximal convoluted tubule have:
Respuesta
-
More rapid transcellular transport and leakier paracellular pathways.
-
Less rapid transcellular transport and leakier paracellular pathways.
-
More rapid transcellular transport and tighter paracellular pathways.
-
Less rapid transcellular transport and tighter paracellular pathways.
Pregunta 6

1
-
2
-
3
-
4
Pregunta 7
Pregunta
A urinary osmolality of 60-70mosm/kg, with a 15mL/min rate of flow would indicate a lack of anti-diuretic hormone (ADH).
Respuesta
- True
- False
