how much blood can a human lose before dying
The body can normally lose 1 pint of blood (usual amount given by donors) without harmful effects. A loss of 2 pints may cause shock, a loss of 5 to 6 pints usually results in death.. Typically, an adult human body contains about 10 to 12 pints of blood, and can expire from the loss of as little as 25% of it.
