micções

Micções refers to the act of urination, the process by which the body expels urine from the bladder. This is a vital bodily function that helps to remove waste products and excess fluid from the body. The process involves a complex interplay of the urinary system, including the kidneys, ureters, bladder, and urethra.

The kidneys filter waste products from the blood, producing urine. This urine then travels down the ureters to the bladder, where it is stored. When the bladder is full, nerve signals are sent to the brain, creating the sensation of needing to urinate. Voluntary control over the sphincter muscles allows for the release of urine through the urethra.

The frequency and volume of urination can vary significantly among individuals and can be influenced by factors such as fluid intake, diet, activity level, and certain medical conditions. Changes in urination patterns, such as increased frequency, urgency, pain, or blood in the urine, can indicate underlying health issues and may warrant medical attention. Maintaining adequate hydration is crucial for healthy urinary function.
