How Many Quarts of Blood Are in the Human Body?

The American Red Cross reports that an adult human has about 10 pints of blood in his body, which converts to about 5 quarts. When a person donates blood, he typically only provides 1 pint per donation.

According to New York Hospital Queens, human blood contains plasma, which is 90 percent water and is responsible for carrying essential vitamins, electrolytes and proteins throughout the body. Blood also consists of red blood cells, which gives blood its red color and carries oxygen from the lungs to the body’s cells; white blood cells, which are important in fighting off infection; and platelets, which are responsible for making blood clot after an injury.
