1 The Respiratory System
Medical Terminology

2 Structures of the Upper Respiratory System
Nose Nasal septum Olfactory receptors Paranasal Sinuses Frontal Maxillary Ethmoid Sphenoid Pharynx Nasopharynx Oropharynx Uvula Laryngopharynx Larynx Glottis Epiglottis Thyroid cartilage

3 Structures of the Lower Respiratory System
Trachea (windpipe) Bronchial Tree Alveoli (alveolus= belly) Lungs Lobes R=3; L=2 Respiratory membrane See next slide Mediastinum Also called: interpleural space Pleura (see next slide) Parietal pleura Visceral pleura Pleural space Diaphragm Phrenic nerve

5 Terminology of Respiratory System
Eupnea note: -pnea = breathing Tachypnea Bradypnea Apnea SIDS Dyspnea DOE Hyperpnea Hypopnea Hyperventilation Anoxia Hypoxia Hypercapnea Cyanosis

6 Terminology of Respiratory System
Nose = nas/o or rhin/o Trachea = trache/o Lungs = pneum/o ; pneumon/o; pulmon/o Ventilation Respiration External respiration Inspiration = active Expiration = passive Internal respiration

7 Pathology of Respiratory System
URI’s Rhinitis (rhinorrhea) Pharyngitis Laryngitis Aphonia & dysphonia Pertussis Croup Epistaxis Pleurisy Pleural effusion Hemoptysis Compare to hematemesis COPD Chronic bronchitis Asthma Bronchiectasis Emphysema Pneumoconioses (coni/o = dust) Asbestosis Anthracosis (black lung) Silicosis Berylliosis Byssinosis These cause pulmonary fibrosis

8 Pathology of Respiratory System
Respiratory distress syndrome Pulmonary edema Atelectasis TB (tuberculosis) Pneumonia Also called pneumonitis Cystic fibrosis Pneumothorax Hemothorax

9 Diagnostic & Treatment Procedures
Thoracentesis Thoracostomy Thoracotomy Pneumonectomy Tracheostomy Bronchoscopy Spirometry Skin tests PPD Mantoux Tine Chest Imaging X-ray CAT MRI Scans
