ELI5: Why do your eyes water when you choke on something?

What are the reasons behind your eyes watering when you begin to choke on food or something?

Your body has a defense mechanism that helps when we get dust or sand in our eyes and it'll start to cry. Much like how a dirty wound will bleed a lot, it helps clean it out. Choking along with eating something spicy, biting your tounge, or even getting hit in the face will result in the eyes starting to water to try and make the body feel better.
