Urination demands muscular cooperation

HERE’S THE INTERESTING PART

Emptying the tank is actually a highly orchestrated mechanical event. The detrusor muscle wrapping the bladder must aggressively squeeze to push liquid out, while the sphincters below must simultaneously completely relax. If this delicate coordination fails, the plumbing locks up entirely, trapping the fluid inside despite the overwhelming physical pressure demanding its release.
