some clinics are a place for people with injuries or illness to come and be seen by triage nurse or other health worker. in these clinics, the injury or illness may not be large or dangerous enough to warrant a visit to an emergency room, but the person can be moved to one if they need to be. these clinics sometimes can use equipment such as x-ray machines. doctors at these clinics can send patients to specialists, a doctor who is very good at one kind of medicine.
