The correct sequence of the movement of urea during urine formation is

  • A. convoluted tubule -> glomerulus -> Henle's loop -> Bowman's capsule -> collecting tubule
  • B. Glomerulus -> Bowman's capsule -> convoluted tubule -> Henle's loop -> collecting tubule
  • C. Bowman's capsule -> Henle's loop -> glomerulus -> collecting tubule
  • D. Glomerulus -> Bowman's capsule -> proximal convoluted tubule -> Henle's loop -> distal convoluted tubule -> collecting tubuleCorrect

Explanation

Urea moves through the nephron in the order: glomerulus, Bowman's capsule, proximal convoluted tubule, Henle's loop, distal convoluted tubule, then collecting tubule.
