While comprehensive study of each anatomy and physiology is needed to totally fully grasp the general workings in the human overall body, this textbook will concentrate mainly on anatomy.
The study of physiology unquestionably consists of observation, each While using the naked eye and with microscopes, and manipulations and measurements. Nonetheless, latest developments in physiology ordinarily rely upon cautiously designed laboratory experiments that reveal the capabilities of the various constructions and chemical compounds that make up the human entire body.
