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: -Urinary tract anatomy The urine travels from the kidney to the bladder through tubes called ureters. The urine is stored in the urinary bladder, and then moves through the urethra to be passed out of the body when you urinate.

Detailed explanation-3: -The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.

Detailed explanation-4: -Anatomy of the distal and proximal urethra. Urine flows out of the bladder and leaves the body through the urethra. The part of the urethra that is closest to the bladder is called the proximal urethra. The part that is closest to where the urine leaves the body is called the distal urethra.
