The respiratory system is composed by a set of organs that are involved when breathing. The anatomy of the respiratory tract includes the nose, nasal cavity, pharynx, larynx, bronchi, lungs, alveoli and the diaphragm. There some organs of the respiratory system that are responsible for the process of breathing. The nose, pharynx, larynx, trachea, bronchi, and lungs permit the gas exchange to happen at the cellular level. The air enters through the nose and mouth and it goes into the lungs to supply all the oxygen that the human body needs to work properly.

The pharynx is a tubular structure organ that is located in the neck it communicates the nasal cavity with the larynx and the mouth with the esophagus. The food pass through the pharynx and also the air that comes and goes from the lungs because the pharynx is part of the digestive and respiratory system. The pharynx is composed by nasopharynx, oropharynx and laryngopharynx. In the other side, the larynx is a tubular organ with muscle structure of cartilage and is the one that connect the pharynx with the trachea. The larynx is located above the trachea and it is formed by the hyoid bone, which acts as like a suspensory apparatus. The larynx contains the vocal cords, fundamental structures to allow phonation. The vocal cords laying down into the two characteristics according to the position they take. If they adopt the position of breathing the vocal cords open toward the sides and the air circulates freely and if they adopt the position of phonation the vocal cords approaches and the air hit them. The larynx is part of the upper respiratory system (Health, MD, …show more content…
The nurse should assess the face, the neck, chest and the abdomen. In the inspection the professional should look for evidence of respiratory distress, breathlessness, cough, wheeze, recently weight loss, tremor, cyanosis, tobacco staining, Cushing syndrome, anemia, possible apical lung cancer (Horner 's syndrome), any possible tracheal obstruction, lymphadenopathy, superior vena cava obstruction. When palpating the professional will use the index finger to feel the trachea and to see if the trachea feels in the middle, chest expansion, when assess tactile vocal fremitus, use the ulnar side of the hand, by the hypothenar eminence with the palms facing upwards. Place it at various levels over the back, each time asking the patient to say "ninety-nine". Note how the sound is transmitted to the hand. Tactile vocal fremitus is increased over areas of consolidation and decreased or absent over areas of effusion or collapse. Feel for the apex beat of the heart; it will be displaced if the mediastinum is displaced or distorted. In the Percussion it is usual to use the middle finger of the dominant hand to check the chest, clavicle, lobes of the lungs front and back except the middle lobe, the heart, hyper-resonant or dull sounds of hyperinflation or pneumothorax. The rest of the chest is percussed by placing the non-dominant hand on the chest and
