Usually you probably would not pass out when a little bit of blood is drawn but if large quantities are taken out then your body doesnt have enough blood to function. Your brain needs blood to function as well as all the other organs. Eventually then your body just sends the blood away from places that are not as important and they send it to the heart and brain and eventually that may run out a little and you pass out
