How do horses swallow there food?

Just like a human! But if your thinking about how they chew there food that's a different story! When horses chew their food instead of chewing they grind their food and when they do this after some time it will sharpen their teeth! If you dont get this fixed on a horse you will have some major problems with that horse! You wont be able to put the bridle on, your horses gum's will get cut up, your horse wont eat, and it would be very irritating for a horse! Wouldn't be irritating if you had such sharp teeth that you could not eat!?
