The average adult human body contains about 10 to 12 pints of blood, though this amount varies based on factors such as age, sex, body size, and overall health. Typically:
- Adult males have around 12 pints (about 5.7 liters) of blood.
- Adult females have about 9 to 10.5 pints (around 4.3 to 5 liters) of blood.
- Blood volume accounts for roughly 7–8% of an adult’s body weight.
Children and infants have proportionally less blood, with infants having about 9–10% of their body weight as blood, and children about 8–9%
. In summary, the human body generally holds between 8 and 12 pints of blood, with an average adult having approximately 10.5 pints
