Explanation:
Detailed explanation-1: -The internal urethral sphincter relaxes, allowing for urine to pass out of the bladder into the urethra. Both of these reactions are involuntary. The external urethral sphincter is voluntary. It must be relaxed for urine to flow through the urethra and outside the body.
Detailed explanation-2: -What has to happen to the external urethral sphincter to allow urination? The external urethral sphincter must be consciously relaxed to allow urination.
