Humans. A typical adult has a blood volume of approximately 5 liters, with females and males having approximately the same blood percentage by weight (approx 7 to 8%) [1][2] Blood volume is regulated by the kidneys. Blood volume (BV) can be calculated given the hematocrit (HC; the fraction of blood that is red blood cells) and plasma volume (PV ...
The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University...
On average, though, the adult human body contains around 10.5 pints of blood. Put another way, that's about five liters or 1.3 gallons. To put those numbers into context, that's somewhere around 8-10% of the average adult's body weight.
The amount of blood circulating within an individual depends on size and weight, but the average human adult has nearly 5 liters of circulating blood. Women tend to have a lower blood volume than men. However, a woman's blood volume increases by roughly 50% during pregnancy.
The blood plasma volume totals of 2.7–3.0 liters (2.8–3.2 quarts) in an average human. It is essentially an aqueous solution containing 92% water, 8% blood plasma proteins , and trace amounts of other materials.
The amount of blood in the human body varies based on age, weight, and sex. An adult male weighing about 200 pounds can have almost 6 liters, or a little over 12 pints, of blood while an adult ...
Blood generally accounts for 8% of the human body weight. The average adult has a blood volume of roughly five liters (1.3 gal). By volume, red blood cells constitute about 45% of whole blood, plasma about 54.3%, and white cells about 0.7%, with platelets making up less than 1%.
That 1.2 to 1.5 gallons is equivalent to 4.5 to 5.5 liters: Blood donors typically give about one pint, or a half-liter, at a time without any serious effects.
