Detailed explanation-1: -Urethra. This tube allows urine to pass outside the body. The brain signals the bladder muscles to tighten, which squeezes urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax to let urine exit the bladder through the urethra.
Detailed explanation-2: -(Left) During normal urine flow, the bladder fills with urine and then empties the urine through the urethra.
Detailed explanation-3: -Your kidneys clean your blood and produce urine, a waste product. From your two kidneys, two ureters move the urine to the bladder, where it’s stored until you urinate (pee). Urine leaves your body through a hole at the end of your urethra. That hole from the inside to the outside is called the urethral meatus.
