Excerpt from Human Anatomy, Physiology, and Hygiene: A Text-Book for Schools, Academies, Colleges In preparing this book, we have aimed to give facts in clear, concise language, and as free as possible from technical terms. All speculations and hypotheses have been omitted as inconsistent with a work of this kind. Our endeavor has been to present the subject, both to the student and to the general reader, in such a form, that the facts may be easily grasped and readily retained. The Anatomy and Physiology are given first; because a knowledge of the location and the functions of the organs of the body, is needed before we can understand how to preserve them in a state of health. We must be acquainted with a law before we can keep it; and we must know the laws which govern our systems, before we can observe them. The body is composed of many organs, each of which performs its part in the economy of the system; yet the functions of these organs are closely connected with each other, and they all act so as to produce a unity and harmony in the whole being.
