Detailed explanation-1: -Urethra. A tube located at the bottom of the bladder that allows urine to exit the body during urination. All parts of the urinary tract-the kidneys, ureters, bladder, and urethra-must work together to urinate normally.
Detailed explanation-2: -The internal urethral sphincter regulates involuntary control of urine flow from the bladder to the urethra, and the external urethral sphincter provides voluntary control of urine flow from the bladder to the urethra.
Detailed explanation-3: -The first part, next to the urinary bladder, passes through the prostate gland and is called the prostatic urethra. The second part, a short region that penetrates the pelvic floor and enters the penis, is called the membranous urethra. The third part, the spongy urethra, is the longest region.
