Answer:
These are the basic steps of urine formation.
Explanation:
The first step comprises creating a filtrate in the glomerulus. 
During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed. 
Waste products will then be secreted by the tubules. 
Whereas, the final stage is the conservation of water that occurs in the renal tubule.
There are four major stages in the formation of urine.
