Final answer:
The medical term for the universal urge to pass urine is micturition.
Step-by-step explanation:
The medical term for the universal urge to pass urine is micturition. Micturition is a proper term for urination or voiding and it results from a combination of involuntary and voluntary actions by the internal and external urethral sphincters. As the bladder fills with urine, the urge to urinate becomes stronger until it is no longer possible to ignore.
