PHYSIOLOGY OF THE URINARY SYSTEM - Reabsorption

Question 1

What is the second step in urine formation

Answer 1

Reabsorption

Question 2

True or False Reabsorption occurs due to passive and active transport mechanisms from all parts of the renal tubules; major portion of reabsorption occurs in proximal tubules

Answer 2

True Reabsorption occurs due to passive and active transport mechanisms from all parts of the renal tubules; major portion of reabsorption occurs in proximal tubules

Question 3

Reabsorption in the proximal tubule results in what?

Answer 3

most water and solutes being recovered by the blood

Question 4

Reabsorption in the proximal tubule results in most water and solutes being recovered by the blood, What does this leave to move on to the loop of henle?

Answer 4

leaving only a small volume of tubule fluid to move on to the loop of Henle

Question 5

What is actively transported out of tubule fluid and into blood?

Answer 5

Sodium

Question 6

What is passively transported out of tubule fluid by means of the sodium cotransport mechanism?

Answer 6

Glucose and amino acids

Question 7

What passively moves into blood due to an imbalance of electrical charge

Answer 7

Chloride, phosphate, and bicarbonate ions

Question 8

What is water reabsorbtion?

Answer 8

It’s movement of sodium and chloride into blood causes an osmotic imbalance, moving water passively into blood

Question 9

Where does approximately one half of urea passively moves out of? Then the remaining urea moving on to where?

Answer 9

renal tubule

loop of Henle
