How does the human body figures out what is “food” and what is a “liquid”, how does it sort it out?

This is something that has always puzzled me.

How does your body understands that these minuscule substances (like spices or seeds) aren’t liquid but instead considered food, and, how does it manages to sort out everything when your stomach has a bunch of things on it at the same time?

It doesn’t sort it out. Everything gets dumped into a pool of acid (stomach), which breaks everything down into small chunks. The acid-food-soup is passed on to a long tube (intestines), where the acid is neutralized (bile), and the nutrients and most of the water gets sucked out. The remaining solids get packed together into a larger mass for disposal later on.
