No one can live with out blood. Blood is the essential thing in human life. The average amount of blood is 4-5 quarts (liters) in female adult humans, and 5-6 quarts (liters) in human adult males. This is about 8% of total body weight. There are some experimental studies in the UK, where they exchange blood for a saline liquid at near freezing temperatures, in order to perform operations on pets that can last as long as an hour. It has not yet been tried on humans.
