What if a jw donates only a "fraction" of his blood to help save others? After all, donating a pint of blood is technically only a small fraction of a persons total blood. Scientists estimate the volume of blood in a human body to be approximately 7 percent of body weight. An average adult body with a weight of 150 to 180 pounds will contain approximately 4.7 to 5.5 liters (1.2 to 1.5 gallons) of blood.
So then a pint of blood is only 1/12 or 8.3 percent (a fraction) of the total blood in the average person
Is a "fraction" of blood the same as blood "fractions"? IMHO---yes!
just saying!
