An understanding of physiology is of central importance in medicine and all of the related health sciences, including nutrition. It is also important to recognise that the modern science of biochemistry—and all its offshoots, including molecular biology and the various omics technologies—grew from physiology. Biochemistry, the chemistry of life, which is fundamental to nutrition and metabolism, developed as an offshoot of physiological chemistry, the chemistry of processes occurring in living animals. The scope of physiology ranges from understanding events at the molecular level (e.g. how muscles contract or how cells sense nutrients) to the integrative physiology of organs and systems (e.g. the brain and the cardiovascular and respiratory systems) and how they are regulated and adjust to stress or change (e.g. in response to exercise or to environmental extremes such as the microgravity of space flight). The emphasis of physiology is on the integration of molecular, cellular, system and whole-body function. Understanding normal function allows prediction of how the organism will respond to any stimulus or stress that is applied.
