The nephron segment responsible for bulk reabsorption of useful solutes and water:
- A. proximal convoluted tubule
- B. Bowman capsule
- C. renal pelvis
- D. ureter
Which nephron segment reabsorbs all glucose and amino acids under normal conditions?
- A. Ascending limb of Henle
- B. Proximal convoluted tubule
- C. Collecting duct
- D. Ureter
Which part of the loop of Henle is highly permeable to water?
- A. Both limbs equally
- B. Ascending limb
- C. Descending limb
- D. Neither limb
What is a major function of the ascending limb of the loop of Henle?
- A. Storage of urine
- B. Reabsorption of water without salt movement
- C. Filtration of blood cells
- D. Reabsorption of electrolytes while remaining relatively impermeable to water
Which nephron region carries out extensive reabsorption of bicarbonate, sodium and water and also secretes hydrogen ions and ammonia?
- A. Proximal convoluted tubule
- B. Bowman's capsule
- C. Renal pelvis
- D. Ureter
The proximal convoluted tubule normally reabsorbs
- A. most filtered water and sodium along with nearly all glucose and amino acids
- B. only urea and no useful solutes
- C. no water
- D. only proteins larger than albumin
A drug blocks sodium chloride reabsorption in the ascending limb of Henle. Which renal function is most directly weakened?
- A. Filtration of plasma proteins
- B. Establishment of the medullary osmotic gradient
- C. Contraction of the urinary bladder
- D. Formation of erythrocytes
Filtrate enters the descending limb of Henle and moves into a progressively more concentrated medulla. What happens to the tubular fluid?
- A. No exchange occurs
- B. Salt enters rapidly and the filtrate becomes dilute
- C. Water leaves, so the filtrate becomes more concentrated
- D. Large plasma proteins are filtered into the tubule
Which tubule segment is especially important for conditional reabsorption of sodium and water under hormonal control?
- A. Afferent arteriole
- B. Bowman's capsule
- C. Glomerulus
- D. Distal convoluted tubule
Given below are two statements : Statement I : In the nephron, the descending limb of loop of Henle is impermeable to water and permeable to electrolytes. Statement II : The proximal convoluted tubule is lined by simple columnar brush border epithelium and increases the surface area for reabsorption. In the light of the above statements, choose the correct answer from the option given below :
- A. Both Statement I and Statement II are true
- B. Both Statement I and Statement II are false
- C. Statement I is true but Statement II is false
- D. Statement I is false but Statement II is true
Common mistakes in What each part of the tubule does
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Believing the filtration barrier prevents useful molecules from entering the filtrate.
- Assuming damage to any nephron segment automatically prevents glomerular filtration.
- Reverses the water permeability of ascending and descending limbs.
- Places ADH action mainly at the glomerular filtration barrier.
