<unk>  is the applied<unk>  dealing with health, and it includes many subdisciplines.
There are two approaches to<unk> : the study and research of the human body and health-related issues to understand how humans (and animals) function,  and the application of that knowledge to improve health and to prevent and cure diseases.
Health research builds upon the basic<unk> s of biology, chemistry, and physics as well as a variety of multidisciplinary fields (for example medical sociology). Some of the other primarily research-oriented fields that make exceptionally significant contributions to<unk>  are biochemistry, epidemiology, and genetics. See also life<unk> s and life<unk>  academic disciplines.
Applied<unk> s also endeavor to better understand health, but in addition they try to directly improve the health of individuals and of people in general.  Some of these are: biomedical engineering, biotechnology, nursing, nutrition, pharmacology, pharmacy, public health, psychology, physical therapy, and medicine.  The provision of services to improve people's health is referred to as health care (see below).  See also branches of medicine.
The<unk> s industry, a multi-billion dollar buiness sector, is a cross-section of the life<unk> s and the health care and medical diagnostics industries.
