The reason that humans can throw up but horses cannot throw up is because the horse has a powerful cut off valve that prevents the horse from throwing up.

A horse can gag but the powerful cut off valve inside the horse will close to stop the horse from vomiting.

If the horse does vomit then it will die soon afterwards because a horse can actually throw up and sometimes the horse does throw up when they are dying or about to die.

But not all horses will throw up when they die or about to die.

Also the horses esophagus meets the stomach at an angle which helps with the cut off function when valve closes.

If a horse manages to throw up then they are very sick so it's never good if you see a horse actually throw up.
