A hospital is a medical facility that provides a wide range of medical services to people who are sick or injured. Hospitals usually have many different departments, including emergency care, intensive care, surgery, radiology, laboratory services, and more. They also typically have a staff of physicians, nurses, and other healthcare professionals who work together to provide high-quality medical care to patients. Hospitals can be owned and operated by the government, non-profit organizations, or for-profit companies. They can range in size from small community hospitals to large teaching hospitals with specialized services and research programs.
