It is the application of natural philosophy to Anatomy, and may very well be defined A philosophic knowledge of the human body, or a science of all the conditions arising from the structure of its parts. It has a foundation both in Anatomy and Philosophy. Anatomy, in a more limited view, considers the structure of the dead body only; but Physiology teaches the functions of the living body. The distinction will he more easily apprehended from observing, that a person may be a good practical Anatomist, and yet be ignorant of Physiology; but it is impossible to be a good Physiologist, without being an able Anatomist.
The great stock of literature, as well as genius, which is requisite to become an adept in this science, and the important nature of the subject it treats of, point out its dignity and excellency.
As every disease we labour under is a disorder of the vital, animal, or natural functions; a thorough acquaintance with these in their found state is implied before we can pretend to understand their morbid affections, or how to remedy them.
Physiology gives us the clearest light in the cure of diseases, which is the grand object of all our inquiries in medicine. The study of it is most entertaining, and engages our closest attention from the many curious subjects with which it abounds.
