How Many Pints Of Blood in The Human Body


There are between 10 to 12 pints of blood in a human body. Estimated total blood volume for an adult is approximately 60-65 ml/Kg body weight. Children have approximately 70 ml/kilogram body weight and obese patients approximately 55ml/kilogram body weight.

The average human body has 5.6 liters of blood, which converts into 11.2 (average) pints of blood children under the age of 13 may have around 8 or lower. Men can vary between 10 and 12 pints depending on size, while woman are 8-10, again depending on size.

  • Men on avarege have about 10-12 pints
  • Women on avarege have about 8-10 pints

You can die from losing as little as 1 pint (sheer shock on this one), to 4-5 pints putting you in hypovolemia. Now, you can lose even more than that, the threshold comes in that the heart can’t be empty, it kinda stalls the engine so to speak.You could technically lose up to 7 pints, but you would have to have no flow to your arms or legs, and even then you would probably be unconscious. This is affected by age for example a 10 year old has around 7 pints and a newborn has about half a pint however this does vary person to person.
