How many CC are there in human blood?

The total weight of a normal human body accounts for about 8% of the body weight. A person weighing 60 kilograms has about 4800 milliliters of blood. Under normal circumstances, these blood do not participate in blood circulation, and 1/5-2/5 blood is stored in liver, spleen, lung and subcutaneous capillaries for later use. People are used to calling this a "small blood bank" of the human body. When the human body is engaged in strenuous activities, it can lose a little blood, and the blood in the blood bank will be released after cooling to participate in blood circulation and maintain the normal physiological function of the human body.
