Question

Loop of Henle is associated with

• A. Excretory system
• B. Respiratory system
• C. Reproductive system
• D. Digestive system

Answer 1

The correct option is A Excretory system

The nephrons are the functional unit of excretory organs, i.e., kidneys. Each nephron has two parts the glomerulus and the renal tubule. The renal tubule begins with a double walled cup-like structure, called as Bowman's capsule, which encloses the glomerulus.

Glomerulus along with Bowman's capsule is called as the Malpighian body or renal corpuscle. The tubule continues further to form a highly coiled network proximal convoluted tubule (PCT).

A hairpin-shaped Henle's loop is the next part of the tubule, which has a descending and an ascending limb. The ascending limb continues as another highly coiled tubular region, called as distal convoluted tubule (DCT).

The DCTs of many nephrons open into a straight tube called as collecting duct, many of which converge and open into the renal pelvis through medullary pyramids in the calyces.
