The human body's blood makes up about 8% of its weight.
A 100-jin adult has about 4000 milliliters of blood. If it's a 200-jin overweight person, having 8000 milliliters of blood inside is not surprising.
Most adults have a normal blood volume of around 5000 to 6000 milliliters.
Taking an adult with 4000 milliliters of blood as an example, actually only about 70% of this blood, at most 80%, is truly circulating within the body.
The remaining 30% of the blood is stored in various tissue cells within the body.
When our body is injured and loses 500 milliliters of blood. Do you think the blood in the vessels will decrease?
It will not.
After the blood system in the body senses a decrease in the blood volume, it will quickly mobilize body fluids to replenish it.
Most of our bodies are made of water.
The water content in newborns can even be as high as 80%, and in adults, it's slightly lower, around 60%.
