Which tube transports urine from the bladder to the outside of the body?

The urethra is the tube responsible for transporting urine from the bladder to the exterior of the body. It plays a vital role in the urinary system, allowing waste to be excreted. The bladder stores urine until it is ready to be expelled, and when it contracts, urine is pushed into the urethra.

In contrast, the ureter is a tube that carries urine from the kidneys to the bladder, while the oviduct (also known as the fallopian tube) is involved in the female reproductive system, facilitating the transport of eggs from the ovaries to the uterus. The uterus itself is an organ where a fertilized egg can develop during pregnancy. Hence, the urethra stands out as the correct option for the role of transporting urine to the outside.
