The prostate gland.
A opening between the tube leading from the kidney to the bladder
The tube from the bladder to the body's opening is called a urethra. The tubes from the kidneys to the bladder are called ureters.
The cloaca is the opening in the skin of snakes and lizards - which leads to the reproductive organs, and the bladder/bowel. It is situated at the base of the tail.
The internal urethral sphincter is a smooth muscle located at the neck of the urinary bladder and surrounds the opening of the urethra. It helps in controlling the flow of urine from the bladder to the urethra.
In males, the urogenital opening is connected to the urethra, which carries urine from the bladder and semen from the reproductive system. In females, the urogenital opening is connected to the urethra (for urine excretion) and the vagina (for reproductive functions).
I'm assuming you mean 'cloaca' - In which case, it's the opening at the base of the tails of reptiles which leads both to the rectum/bladder, and reproductive organs.
Men, the tub in the penis is used for both functions.
my friends snake poop is brown but mine is yellow and wet REALLY SMELLS
A urethral opening is the opening of the end of the penis to comes out the sperm cell and the bladder. =)
The opening of the female reproductive system is called the cervix.
The urethra in male pigs is the structure that transports both wastes (urine) and reproductive cells (sperm) to the outside of the body. It serves a dual function of carrying urine from the bladder and sperm from the testes through the reproductive system.
The external opening in the female reproductive system is the introitus. The introitus is the opening of the vagina where it meets the outside world.
