How Many Pints Of Blood in The Human Body

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.

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 of blood , 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.

How Much Blood Do We Have In The Human Body?

Did you know that we have enough blood in our body to fill almost a 4-liter jug of milk? In fact, it is estimated that the average adult has between 4.5 to 5.5 liters of blood circulating inside their body . Although this amount varies depending on the stage of life in which we are, and our gender. For example, men usually have between 4.25 and 5.67 liters, while women have about 4.25 liters.

However, when we are children we do not have the same amount of blood as in adulthood, especially until we are 5-6 years old. Mainly because children are smaller in size, and because their bones, muscles and organs tend not to weigh as much, their blood makes up a vastly greater percentage of their body weight, compared to adults.

However, newborn babies have between 75 and 80 milliliters of blood for every kilogram of body weight. We can take as an example a newborn baby that weighs between 2.3-3.6 kg. When it is this weight, it will originally only have about 0.2 liters of blood in its entire body, a similar amount of blood that a 4.5 kg cat would have in its body. Dogs, of course, have a little more blood: around 86 ml per kilogram, so that a dog weighing 36 kg has 3 liters of blood.

In the case of children, however, it usually has between 70 and 75 ml of blood for every kilogram of body weight.

Whereas, in the case of pregnant women, to help their babies in development and growth, they have 30 to 50 percent more blood volume than non-pregnant women, which is about 1 to 1, 50 additional liters of blood.
