The term "urinary" refers to anything related to the urinary system, which is responsible for producing, storing, and eliminating urine. This system includes organs such as the kidneys, ureters, bladder, and urethra. The kidneys filter waste and excess substances from the blood, forming urine that is then transported to the bladder for storage. When the bladder is full, signals are sent to the brain, prompting the urge to urinate. The process of urination involves the relaxation of the bladder muscles and the contraction of the urethra to expel urine from the body. This system plays a crucial role in maintaining the body's fluid balance and removing waste.
