Physiology
Physiology (; from Ancient Greek φύσις (physis), meaning 'nature, origin', and -λογία (-logia), meaning 'study of') is the scientific study of normal mechanisms, and their interactions, which work within a living system. A sub-discipline of biology, its focus is in how organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical functions that exist in a living system. Given the size of the field, it is divided into, among others, animal physiology (including that of humans), plant physiology, cellular physiology, microbial physiology (microbial metabolism), bacterial physiology, and viral physiology.

I don't think I know enough to say, well, here's the plan. It's not my specialty.... But I don't think there's any way not to have that debate about how much we're going to spend on health care.... In finding our way forward, we've got to be able to find ways to deliver the quality care that everyone expects and that we're capable of providing to the maximum number of people.
