Question

Rearrange the following parts of a nephron in the order in which fluid flows through the nephron.

• A. $\mathrm{Bowman}\text{'}s\mathrm{capsule}\to \mathrm{Proximal}\mathrm{tubule}\to \mathrm{Loop}\mathrm{of}\mathrm{Henle}\to \mathrm{Distal}\mathrm{tubule}\to \mathrm{Collecting}\mathrm{duct}$
• B. $\mathrm{Proximal}\mathrm{tubule}\to \mathrm{Loop}\mathrm{of}\mathrm{Henle}\to \mathrm{Distal}\mathrm{tubule}\to \mathrm{Bowman}\text{'}s\mathrm{capsule}\to \mathrm{Collecting}\mathrm{duct}$
• C. $\mathrm{Loop}\mathrm{of}\mathrm{Henle}\to \mathrm{Proximal}\mathrm{tubule}\to \mathrm{Distal}\mathrm{tubule}\to \mathrm{Bowman}\text{'}s\mathrm{capsule}\to \mathrm{Collecting}\mathrm{duct}$
• D. $\mathrm{Bowman}\text{'}s\mathrm{capsule}\to \mathrm{Distal}\mathrm{tubule}\to \mathrm{Proximal}\mathrm{tubule}\to \mathrm{Loop}\mathrm{of}\mathrm{Henle}\to \mathrm{Collecting}\mathrm{duct}$

Answer 1

The correct option is A

$\mathrm{Bowman}\text{'}s\mathrm{capsule}\to \mathrm{Proximal}\mathrm{tubule}\to \mathrm{Loop}\mathrm{of}\mathrm{Henle}\to \mathrm{Distal}\mathrm{tubule}\to \mathrm{Collecting}\mathrm{duct}$

The following is the order of flow of fluid:

1. Bowman's Corpuscle - The nephron begins as a blind, cup-like pocket called Bowman's capsule. The capsule envelopes a bundle of capillaries called the glomerulus. Bowman's capsule and glomerulus make up the renal corpuscle.
2. Proximal convoluted tubule - is the longest and widest segment of the nephron.
3. Loop of Henle - The cells of the descending limb of the loop are simple squamous and give this region of the tubule a narrow diameter.
4. Distal convoluted tubule - Following the loop, the nephron continues as the distal tubule.
5. Collecting duct - Collecting duct is a long, straight tube where the maximum reabsorption of water takes place to produce concentrated urine.
