What is the name of the tube leading from the bladder to an exit from the body?

The tube that leads from the bladder to an exit from the body is known as the urethra. Its primary function is to transport urine stored in the bladder out of the body during urination. The urethra also serves a secondary role in males, as it is the channel through which semen is expelled during ejaculation.

Understanding the anatomy and functions related to the urinary system is essential for recognizing the distinct roles of different structures. In this context, the ureter, which is a separate tube from the kidneys to the bladder, is often confused with the urethra but functions as a pathway for urine rather than a means of exiting the body. The bladder neck refers to the region of the bladder that connects to the urethra and does not describe the tube itself. The prostate is a gland that surrounds the male urethra and has functions related to reproductive health, but it is not the tube connecting the bladder to the exterior. The accurate choice reflects a fundamental understanding of the urinary anatomy and its functions.
