Final answer:
Blood doping is the practice of injecting additional red blood cells (RBCs) to enhance sports performance. Autologous blood donation refers to a blood donation intended to be used by the donor in the future.
Step-by-step explanation:
The subject of this question is Biology, specifically related to blood donation and blood types.
Blood doping is the practice of injecting additional red blood cells (RBCs) into an individual to enhance performance in sports. The source of the cells can be either from the recipient (autologous) or from a compatible donor (homologous). Autologous blood donation refers to a blood donation that is intended to be used later on the donor.
Autologous blood donations are commonly used in medical procedures such as surgeries to ensure that the patient has a sufficient supply of their own blood available if needed.
