Assuming that there were a "law of the body" (as proposed by Professor Meredith Render) which allows persons to own their own bodies in the same way they can own property, then what would constitute a "fair price" for the following body parts, taking into account likely uses, the cost to donor, the benefit to the recipient, and public policy considerations.

1. Reproductive cells (spermatozoa or ovum)
2. A pint of blood (whole blood or broken down into red cells, platelets, and plasma)
3. A kidney
4. A chunk of liver sufficient to serve as a transplant
5. A cornea
6. A heart
7. A lung
