(a) Ultrafiltration-Glomerulus
(b) Concentration of urine-Collecting duct
(c) Transport of urine-Ureter
(d) Storage of urine-Urinary bladder

Answer 1

answer:

b) concentration of urine- Collecting dust

Answer 2

The incorrect pair is- (b) Concentration of urine - Collecting duct.

To answer this question, let us first understand what a urinary system is?

• The urinary system is involved in the formation of urine. It filters the blood and forms concentrated urine as a by-product which is stored and then excreted out of the body. Different parts of the urinary system perform different functions.

Parts of the urinary system and their functions:

1. A pair of kidneys is the main part of the urinary system that is made up of nephrons.

• It consists of the glomerulus that is involved in the filtration of blood that runs through it. Thus, the glomerulus does ultrafiltration and initiates the formation of urine.
• The collecting duct collects the urine and delivers it to ureters.
• The loop of Henle is involved in the formation of concentrated urine by maintaining the osmolarity of medullary interstitial fluid and reabsorption of water.

2. Ureters transport the urine to the urinary bladder.

3. Urinary bladder stores the urine till the urine is excreted out of the body through the urethra.
