How many liters of blood does the human body have?

The question we are asking is probably very recurrent, but it is still a major doubt for many people who do not know for sure how many liters of blood we have in the body, and how it changes depending on whether we are small or we are in advanced age.

These are the liters of blood that we have in our body, by ages

As a general rule, the average adult usually has between 4.5 and 5.5 liters of blood circulating inside the body. But we must always emphasize that it depends on the time of life we are talking about, and it also depends on gender, because it is not the same because of the natural physical conditions of men and women, as we say, always in a generalized way:

– Men usually have between 4.25 and 5.67 liters.

– A woman has about 4.25 liters of blood.

How much blood do children have in their bodies?

And what happens when we are children? Well, we do not even come close to having the same amount of blood as in adulthood, especially until we reach the first years of age, usually in the range from 4 to 7 years old, inclusive. As a general rule, they have between 70 and 75 ml of blood per kilogram.

This is mainly due to the fact that children are smaller, of course, and as they grow older they produce more. The fact that the bones and muscles of the smallest children weigh much less than those of adults also helps. Babies have between 75 and 80 milliliters of blood for each kilogram of body weight.
