Many first-aid materials suggested that not to tilt head upwards to treat 
nosebleed, since this will cause the blood to flow down the throat, into 
the stomach and cause vomit.

Why is it so?

What kind of reactions or 'activities' taken place when blood reaches 
stomach which causes nauseate?

Thanks.
