Answer 1

The correct option is D A-glomerulus,

B- proximal convoluted tubule,
C-Henle's loop,
D-distal convoluted tubule,
E-collecting duct
Kidney has several millions of functional and structural units known as nephrons. Each nephron has the glomerulus and the renal tubule. Glomerulus is a tuft of capillaries formed by the afferent arteriole. Renal tubule can be divided into proximal convoluted tubule (PCT), Henle’s loop, distal convoluted tubule (DCT) and collecting duct.

PCT is the highly coiled structure found next to Bowman’s capsule. Around 70-80 percent of electrolytes and water are reabsorbed by this segment.

Henle’s loop is a hairpin like structure. It plays a role in maintenance of high osmolarity of medullary interstitial fluid.

Distal convoluted tubule (DCT) is another highly coiled tubule which finally opens into collecting duct.

Collecting duct is the long duct extends from the cortex of the kidney to the inner parts of the medulla

Hence, the correct labelled diagram is:
A-glomerulus,
B- proximal convoluted tubule,
C-Henle's loop,
D-distal convoluted tubule,
E-collecting duct.
