Prostatic urethra

So when you go pee, the pee comes out of a little tube that travels from your bladder down to your private parts. But boys have a special little part called the prostate that's like a little bump right under the bladder. The tube that carries pee through the prostate is called the prostatic urethra. It's like a little tunnel that the pee goes through to get out. Sometimes when boys get older, their prostate can get bigger and it might make it harder to pee, but that's a different story!
