Average adults enjoy between 4 - 6 Liters of blood.
There are complex formulas that can be used to estimate the blood volume of an individual that account for hematocrit, stage, weight, and other factor.
Basically, larger people hold more blood then smaller ethnic group.
Total blood volume = Plasma vol * 100/ 100-hematocrit.
Plasma vol can be measured using dyes- Evan's blue (T- 1824) 3500ml. Hematocrit is the ratio of ccells to plasma in our body- arounr 38 to 40%. Therefore, blood vol. comes to 5.6 l.
