ELI5 how when you have cold, your nose has almost endless amount of mucus, no matter how many times you blow your nose.

You have glands in your nose that produce mucus. Typically this is a slow production meant to keep your nostrils moist amongst other things. When you get an infection like a cold which finds its way into the nasal tissue, your body signals those glands to go into overdrive in an attempt to wash away and expel the invading microorganisms. The production of mucus stays high until the immune response slows down due to not finding any more invaders to fight.
