Final answer:
Urinary incontinence is the inability to expel contents from the bladder, affecting quality of life and possibly indicating underlying health problems.
Step-by-step explanation:
The inability of the bladder to expel its contents is known as urinary incontinence. This condition can result from various issues, including loss of pelvic floor muscle support, overactive bladder, or neurological conditions. Micturition is the medical term for urination, and it involves both involuntary and voluntary actions.
The detrusor muscle is critical for emptying the bladder, but its strength can diminish with age, leading to difficulties in bladder emptying. In some cases, increased abdominal pressure may be used to aid in micturition. Urinary incontinence may significantly affect quality of life, leading to distress and embarrassment for the individual.
