Question

Which of the choices below gives the correct order in which fluid passes through the nephron?

a) V. proximal convoluted tubule
b) W. collecting duct
c) X. distal convoluted tubule
d) Y. Bowman's capsule
e) Z. Loop of Henle"

Answer 1

The correct order in which fluid passes through the nephron is from Bowman's capsule, to the proximal convoluted tubule, then the loop of Henle, followed by the distal convoluted tubule, and finally, the collecting duct.

Step-by-step explanation:

The correct order in which fluid passes through the nephron is as follows:

1. Bowman's capsule (Y)
2. Proximal convoluted tubule (V)
3. Loop of Henle (Z)
4. Distal convoluted tubule (X)
5. Collecting duct (W)

After the blood is filtered in the glomerulus, the filtrate enters the Bowman's capsule. From the Bowman's capsule, the fluid passes through the proximal convoluted tubule, then the loop of Henle, followed by the distal convoluted tubule, and finally, the collecting duct.

The correct order in which fluid passes through the nephron is: d) Bowman's capsule, a) proximal convoluted tubule, e) Loop of Henle (which includes both the descending and ascending limbs), c) distal convoluted tubule, and finally b) collecting duct.

The nephron is the functional unit of the kidney where blood filtration and urine formation take place. First, blood enters the glomerulus within the Bowman's capsule where filtration occurs. The filtrate then flows into the proximal convoluted tubule where reabsorption and secretion of various substances alter its composition. Next, the Loop of Henle concentrates the filtrate by allowing water and solutes to be reabsorbed into the bloodstream. Following the Loop of Henle is the distal convoluted tubule where additional fine-tuning of the filtrate's composition happens. The final stage is the collection of the refined urine in the collecting ducts, which ultimately leads to the renal pelvis and onto the bladder for excretion.
