Anatomy and physiology : designed for academies and families . y animated conversation ; the bloodwell purified; the muscular system duly exercised; the foodtaken at regular periods, and properly masticated. What caution relative to food in-warm weather? When is digestionmost perfect ? CHAPTER VII ORGANS OF RESPIRATION. The organs of respiration are the lungs, the larynx, and thetrachea. The ribs, the diaphragm, and several muscles, arealso subservient to the respiratory process. The thorax, sometimes called the chest, is bounded poste-riorly, by the spinal column, posterior extremity of the ribs,and the intercostal muscles ; laterally, by the ribs and inter-costal muscles ; anteriorly, by the sternum, anterior extremityof the ribs, and the cartilages which connect the ribs to thesternum; inferiorly, by the diaphragm, which separates thiscavity from the abdomen. The natural form of the chest isa truncated cone. The correct form of the chest, and theposition of the organs contained in it, are represented by thethree following engravings. Fig. Name the organs of respiration. How is the thorax bounded ? Itsform ? What does Fig. 107 exhibit ? ORGANS OF RESPIRATION. 157 Fig. 107.
