Parts of the Respiratory system UPPER Nasal Cavity Mouth Pharynx Larynx LOWER Bronchi Sternum Heart Secondary Bronchi Lung Diaphragm Epiglottis Esophagus Trachea

Upper Respiratory Tract Nose Nostrils/nares Nasal turbinates/ conchae (warm blooded animals) Nasogastric tube Mucus membranes Cilia Olfactory receptors Tonsils

Conchae

Upper Respiratory tract continued… Sinus Types Frontal Maxillary Sphenoid Feline, Bovine, Equine, Swine Palatine Ruminants, Equine Lacrimal Swine, Ruminants Conchal Swine, Ruminants, Equine

Lower Respiratory System Trachea Air passage Bronchi Branches of lung Alveoli Most gas exchange Thorax Location of lungs Pluera Membrane containing lungs Diaphragm Aides in breathing, separates the peritoneal and thoracic cavity

Breathing Overview Video http://www.nlm.nih.gov/medlineplus/ency/anatomyvideos/000018.htm

Common Procedures Bronchoalvelor lavage Percussion Radiography (Xray) Collection of fluid via fluid flush Percussion Tests density by tapping on body surfaces. Fluid filled vs. air filled differ in sound (liquid in lungs?) Radiography (Xray) Thoracocentesis Puncture chest cavity to remove fluid

Common Ailments : Respiratory System Aspiration: inhalation of a foreign object Epistaxis: nosebleed Pleural Effusion: accumulation of fluid in the pleural space Pulmonary edema: fluid in the lung tissue Rhinorrhea: nasal discharge Stenotic nares: narrowed nostrils that reduce air flow

Activities Chapter 9 book review: Given later in the week Draw the path of breathing ( Figure 9-9) : Due Monday when you leave Draw the lungs and label their parts. Be able to define what purpose they serve in the respiratory system. Due Monday when you leave Research one respiratory disease Symptoms, Signs, Cause, Treatment, Prevention ID the breed of animal Put on notebook paper, you will be able to use this on your exams.
