INTRODUCTION

Through experimental analysis of the physiological aspects of the human respiratory system, one can truly gain a better understanding of its inner-workings. A deeper look into the anatomy and the physiological mechanisms of the human lungs requires using the knowledge gained from research, lab and coursework of the respiratory system. The respiratory system begins with respiratory airways that lead into the lungs. These airways include nasal passages, pharynx, trachea, larynx, right and left bronchi, bronchioles and clusters of alveoli. The lungs themselves occupy most of the thoracic cavity and each lung is divided into several lobes. The diaphragm and pleural sac are important components to the respiratory system as well. The pleural sac is a thin layer of tissue covering the lungs and the wall of the chest cavity to protect and cushion the lungs.
