Health
science is the branch of science focused on health, and it
includes many subdisciplines.
There
are two approaches to health science: the study and research
of the human body and health-related issues to understand
how humans function, and the application of that knowledge
to improve health and to prevent and cure diseases.
Health
research builds primarily on the basic sciences of biology,
chemistry, and physics as well as a variety of multidisciplinary
fields.
Some
of the other primarily research-oriented fields that make
exceptionally significant contributions to health science
are biochemistry, epidemiology, and genetics.
