What is medical school?

Upon the completion of studies, doctors will go on to medical residency, which is the clinical training among or within medical specialties, like primary care or cardiology. The length of residency depends on the specialty that the doctor chooses. For example, family practice is around two years, and surgery is typically at least five years.
