Precipitation happens in the urinary passages, however the crystals are typically held in the lower calyx of the kidney. \" Which urinary passages are you referring to? How and where is urine formed in the urinary system?

Solution

When precipitation occurs in the urinary passages, the crystals are usually retained in the lower calyx of the kidney. A crystalline deposit tends to grow into crystalline concretions under the action of surface energy, thus forming true primary calculi. Stones of this type soon irritate the wall of the cavity in which they are contained and cause a reactionary exudate. The laminated stone is formed by continued deposition of crystals, coupled with rhythmic precipitation of a foreign colloid derived from the exudate. Stones originating in infected media are formed in a similar manner. Therefore this urinary passage is referring to Urolithiasis: The process of forming stones in the kidney, bladder, and/or urethra (urinary tract).

Each kidney consists of millions of functional units called nephrons. Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.

For better understanding read it

The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra. Urine is used to extract excess minerals or vitamins as well as blood corpuscles from the body. The Urinary organs include the kidneys, ureters, bladder, and urethra. The Urinary system works with the other systems of the body to help maintain homeostasis. The kidneys are the main organs of homeostasis because they maintain the acid base balance and the water salt balance of the blood.
