Urinary bladders are exceptionally highly flexible muscular sacs capable of comfortably holding up to half a liter of liquid, and their internal stretch receptors continuously bombard your brain with urgent signals long before the organ is actually full. the detrusor muscle in the bladder wall allows the organ to expand significantly without bursting, meaning those panicked, emergency signals telling you to find a bathroom immediately are mostly just your nervous system being incredibly overly dramatic. your body is basically lying to you to ensure you do not publicly humiliate yourself, which is a surprisingly considerate gesture from a biological system that routinely fails us in so many other ways. it is a brilliant safety buffer until you are stuck in terrible traffic and fully convinced you are about to medically explode
