Final answer:
Bioethics is the study of moral issues arising in medicine and biomedical research, including concerns like abortion, euthanasia, and clinical trials; it represents a field of applied ethics that requires a multidisciplinary approach.
Step-by-step explanation:
The branch of study of moral issues, questions, and problems arising in the practice of medicine and in biomedical research is called bioethics. Bioethics is an area of applied ethics that tackles a plethora of ethical dilemmas in the medical and research fields, including, but not limited to, patient autonomy, the equitable distribution of medical resources, human experimentation, and challenging end-of-life decisions. Key contemporary topics in this field include abortion, euthanasia, and the ethical conduct of clinical trials. Philosophers and ethicists examine these complex matters from various perspectives to establish moral positions which encompass social obligations, individual rights, and concepts of personhood. Particularly, bioethics engages with pressing real-world scenarios, such as the moral concerns surrounding a patient's right to refuse vaccines or life-saving treatments based on personal beliefs, illustrating the interdisciplinary nature of this field.
