1. Reports about a man who successfully undergone xenotransplantation of a pig heart in replacement of the defective human heart created media attention due to a possible breakthrough attention. However, news has broken that he survived and died after months. Considering your knowledge about evolution and comparative anatomy, do you think it is possible to substitute a pig heart for a human heart? Why? Why not? Explain your answers using what you have learned so far in the subject.

Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.
