The urethra is a structure inside the body that expels urine from the bladder. Its function is to conduct the urine from the bladder for elimination.
The release of urine, known as urination or micturition, is the process by which the body expels waste products and excess fluids from the bloodstream. It occurs when the bladder fills with urine, triggering nerve signals that prompt muscle contractions, allowing urine to flow through the urethra and out of the body. This process is essential for maintaining the body's fluid balance and removing toxins.
