    MANUAL OF PHYSIOLOGY. —*— SECTION I. GENERAL PHYSIOLOGY. CHAPTER L INTRODUCTION. Human physiology deals with the functions of the various parts of the body. The body, as a whole, is made up of different systems, such as the digestive system, the circulatory system, the respiratory system, the muscular and skeletal systems, the excretory system, and the nervous and special sense systems. Each of these has its special functions to perform, but it cannot be too strongly insisted that these systems do not act independently of each other, and that the proper working of one depends upon the harmonious working of the others. The various systems are made up of organs which have no independent action, the smooth working of one organ depend- ing upon the proper functioning of other organs. The organs of the body are composed of tissues, namely— 1. Epithelial tissues. 2. Connective tissues. 3. Muscular tissues. 4. Nervous tissues. These in their turn are essentially composed of cells, held together by a varying amount of intercellular material. Each
