BLOOD GROUP- Normally in a person 5-6 liter blood is there. If due to bleeding one liter of blood is lost then it can easily be compensated. after bleeding spleen[blood bank of the body] contracts and pushes the fresh blood into circulation, heart rate becomes fast, there is excessive thirst. If blood loss is more than this then it will not be compensated and due to less supply of blood to vital organs death may occur.
