In this manual we will study the branch of applied ethics that reflects, deliberates and makes normative and public policy proposals to regulate and resolve conflicts in social life, especially in the life sciences, as well as in medical practice and research that affect life on the planet, both now and in future generations. This notion of Bioethics consists of two aspects: the need for a conceptual approach, since there is no universal definition as such; and, on the other hand, a notion is needed that allows it to be transferred to the operational field and put into practice.
