A more thorough explanation:

NOTA is an abbreviation for the National Organ Transplant Act. It is a law that regulates the donation and transplantation of organs in the United States.

• NOTA prohibits the sale of organs for transplantation.
• NOTA established the Organ Procurement and Transplantation Network (OPTN) to manage the allocation of organs.

The examples illustrate how NOTA is a law that sets rules for organ donation and transplantation. The first example shows that NOTA prohibits the sale of organs, which helps prevent exploitation of vulnerable individuals. The second example shows that NOTA created a system to fairly allocate organs to those in need.
