Question 4

Excretion

Which of the following is the correct route for the movement of materials through the kidney?

  1. A.Glomerulus → Bowman's capsule → Loop of Henle → Collecting tubule → Pelvis
  2. B.Glomerulus → Loop of Henle → Collecting tubule → Bowman's capsule → Pelvis
  3. C.Pelvis → Bowman's capsule → Glomerulus → Loop of Henle → Collecting tubule
  4. D.Bowman's capsule → Glomerulus → Loop of Henle → Collecting tubule → Pelvis
  5. E.Bowman's capsule → Loop of Henle → Glomerulus → Collecting tubule → Pelvis
Show the answer and explanation

Answer: A (Glomerulus → Bowman's capsule → Loop of Henle → Collecting tubule → Pelvis)

Explanation

Blood is filtered in the glomerulus into Bowman's capsule; the filtrate passes along the tubule and loop of Henle to the collecting tubule and then the pelvis.
