uriiniväljalaske
uriiniväljalaske refers to the process of expelling urine from the body. This physiological function is a critical part of the urinary system's role in waste removal and fluid balance. The process begins in the kidneys, where blood is filtered to produce urine, a liquid waste product containing urea, salts, and excess water. Urine then travels down the ureters, two tubes that connect the kidneys to the bladder. The bladder, a muscular organ, stores urine until it is full. When the bladder reaches a certain capacity, stretch receptors signal the brain, triggering the urge to urinate. The voiding reflex, or urination, involves the coordinated action of the bladder muscles (detrusor muscle) contracting and the sphincter muscles relaxing, allowing urine to exit the body through the urethra. Disruptions to this process can lead to various urinary issues, impacting an individual's health and quality of life. Factors such as nerve damage, infections, or structural abnormalities can affect the ability to store or expel urine effectively. Maintaining proper hydration and overall health supports the normal functioning of the uriiniväljalaske system.
