Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Starting from the glomerular capsule, the correct order of the renal tubule regions is ____
A
proximal convoluted tubule, nephron loop (loop of Henle), distal convoluted tubule
B
distal convoluted tubule, proximal convoluted tubule, nephron loop (loop of Henle)
C
nephron loop (loop of Henle), proximal convoluted tubule, distal convoluted tubule
D
proximal convoluted tubule, distal convoluted tubule, nephron loop (loop of Henle)
Explanation: 

Detailed explanation-1: -Glomerulus → Proximal Convoluted Tubule → Collecting duct → Henle loop.

Detailed explanation-2: -Glomerular capsule, proximal convoluted tubule, the loop of Henle, distal convoluted tubule.

Detailed explanation-3: -The renal tubule begins at the glomerular capsule as the proximal convoluted tubule (PCT), continues through the loop of Henle, and turns into a distal convoluted tubule (DCT) before emptying into a collecting duct.

Detailed explanation-4: -Hence the correct order is ‘Glomerular filtration → Reabsorption → Secretion’.

Detailed explanation-5: -proximal convoluted tubule (found in the renal cortex) loop of Henle (mostly in the medulla) distal convoluted tubule (found in the renal cortex) collecting tubule (in the medulla) collecting duct (in the medulla)
