What is the structure that is next to bladder in males?
The urine leaves the bladder through the urethra, and exits the body. (Not to be confused with a similar tubal structure, the ureter, which carries the urine from the kidneys to the bladder.) In human males (and other animals), the urethra runs through the penis, and is also the tube through which semen is carried.
That structure is called as ureter. One each is going to bladder from the kidney. You have the urethra that carry urine from bladder to out side of your body. It is a single tube. You need to remember one term called as uterus. That means part of the female reproductive system, which carry foetus for about nine months.
