I was in surgery earlier and remember when the nurse put injected anesthesia and something else through the IV and I could feel the liquid push itself into my vein and it felt like my vein in my hand to elbow would explode.
That got me thinking, how does my body intake so much liquid like the full IV bag without exploding or peeing on the operating table while I’m knocked out.

Veins aren’t rigid like home plumbing. They are somewhat elastic. Veins expand and contract for many reasons; Cary nutrients, fats, oxygen, and can expand and distribute vaccines and other liquids as necessary.
General answer. I’m at sure others can be more specific and technical.
