Respiratory Pathologies

August 26, 2009

In chapter 8 our book talks about the Respiratory system. I have learned that breath and the breathing process are synonymous with life. Breathing is the most easily observable of the body’s vital signs. Massage therapy also directly affects the respiratory system. By massaging the muscles of respiration, the therapist can perhaps ease a clients breathing. Cells continually use oxygen for the metabolic reactions that release energy from nutrient molecules. The two body systems that cooperate to supply oxygen and eliminate carbon dioxide are the cardiovascular and respiratory system. The respiratory system also helps regulate blood Ph. The respiratory system contains olfactory receptors, filters incoming air, produces sound, and eliminates some water and heat in exhaled air. Air movement and gas exchange are accomplished by the anatomical structures of the respiratory system. The entire respiratory tract is lined with mucous membrane. The lungs are in the thoracic cavity and rest on the diaphragm. The right lung has 3 lobes and is thicker and broader than the left lung because the liver, a large organ, is underneath the diaphragm on the right side. Inside each lung the primary bronchi branch into smaller secondary bronchi. Eventually, the bronchioles branch into alveoli. Between the walls of the alveoli is the respiratory membrane. Pulmonary Ventilation is a mechanical process because it involves muscular contraction, muscular relaxation, and elastic recoil of the alveoli. The diaphragm is the main muscle of inhalation.
