A hospital may be a single building or a number of buildings on a campus. Many hospitals with pre-twentieth-century origins began as one building and evolved into campuses. Some hospitals are affiliated with universities for medical research and the training of medical personnel such as physicians and nurses, often called teaching hospitals. Worldwide, most hospitals are run on a nonprofit basis by governments or charities. There are however a few exceptions, e.g. China, where government funding only constitutes 10% of income of hospitals. (need citation here. Chinese sources seem conflicted about the for-profit/non-profit ratio of hospitals in China)

In addition, there is the department of nursing, often headed by a chief nursing officer or director of nursing. This department is responsible for the administration of professional nursing practice, research, and policy for the hospital. Nursing permeates every part of a hospital. Many units or wards have both a nursing and a medical director that serve as administrators for their respective disciplines within that specialty. For example, in an intensive care nursery, the director of neonatology is responsible for the medical staff and medical care while the nursing manager/director for the intensive care nursery is responsible for all of the nurses and nursing care in that unit/ward.

A medical laboratory or clinical laboratory is a laboratory where tests are usually done on clinical specimens in order to obtain information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease.Clinical laboratories are thus focused on applied science mainly on a production-like basis, as opposed to research laboratories that focus on basic science on an academic basis.
