The urethra is a tube that connects the urinary bladder to the genitals for the removal of fluids from the body.
Urine cytology evaluates this urinary sediment for the presence of cancerous cells from the lining of the urinary tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for urinary tract cancers.
For this process, urine must be collected in a reliable fashion, and if urine samples are inadequate, the urinary tract can be assessed via instrumentation.
Describe the location and function of the urethra as part of the urinarysystem
They are essential in the urinarysystem and also serve homeostatic functions such as the regulation of electrolytes, maintenance of acid–base balance, and regulation of blood pressure (via maintaining salt and water balance).
They serve the body as a natural filter of the blood and remove wastes that are diverted to the urinary bladder.
