The branch of ethics that investigates problems specifically arising from medical and biological practice. These include problems of the nature and distribution of treatment; the sphere of authority of the patient, the physician, and others; the scope and limits of confidentiality; the limits of acceptable intervention and experimentation (see abortion, euthanasia); and the propriety of genetic research and its applications.
