When men pee, are we just allowing the pee to flow out or are we subconsciously pushing it? Also, when we do push it, what’s happening there?
In:
Since humans can pee upside down and even in zero gravity, it stands to reason that something more than gravity is at play. Since we can vary the flow of urine at will, that means the thing causing the flow is under voluntary control – in other words, muscles.
Basically we’re applying pressure to our abdominal muscles near our bladder, ‘squeezing’ it out. Also there is a sort of wall that closes off the connection between your bladder and urethra(pee-pee pipe), when you pee your brain signals to relax that muscle so it can pass through.
For men (and women) the bladder is like a water balloon. As it fills up, it stretches out and the only thing that keeps it from leaking is a muscle that pinches the neck of the balloon. When the bladder is full you can relax the pinching muscle and the stretchy bladder will let out the pee just like a full balloon. When it is not all the way full or if you want to push the pee out faster you can squeeze your abdominal muscles which is like squeezing the back of the water balloon while it is draining.
