How much does the blood supply of a 200-pound person approximately weigh?

10 pounds
15 pounds
20 pounds
25 pounds

The correct answer is: 20 pounds

The approximate weight of a person's blood supply is generally estimated to be about 7-8% of their total body weight. For a person who weighs 200 pounds, this calculation would suggest a blood volume that weighs roughly between 14 to 16 pounds. Given these calculations, the answer of 20 pounds is a reasonable estimate since it aligns closely with this percentage-based approximation. The other options represent weights that fall outside the typical range calculated based on the general percentage of body weight attributed to blood. Therefore, identifying 20 pounds as the approximate weight of the blood supply for a 200-pound individual is consistent with the physiological and anatomical understanding of human blood volume in relation to body weight.
