  1. Just Breathe Respiratory System HST

  2. Functions of the Respiratory System • Take in O2 for use on a cellular level • Expels waste such as CO2 & H2O from the cells • Air flow over larynx make speech possible

  3. Word Parts nas/o alveo/lo sinus/o pneum/o, pneumon/o, pneu epiglott/o atel/o pulm/o pharyng/o cyan/o pulmon/o laryng/o -ectasis tachy- trache/o phon/o thorac/o bronch/o pleur/o -thorax bronchi/o -pnea

  4. The Respiratory Tract • Upper Respiratory Tract = nose, mouth, pharynx, larynx epiglottis, trachea • Lower Respiratory Tract = lungs,bronchi, bronchioles, alveoli Where are these structures located?

  5. Opening of the Respiratory System • Nares- Nares - nasal openings

  6. Nasal Septum Turbinates Separates R & L nares

  7. Functions of the Nose • Mucous membranes -Warm, filter, moisten inhaled air

  8. Cilia • *Move mucous & trapped particles into esophagus

  9. ________ Membranes * line surfaces of resp tract AND * secrete ______ to moisten surfaces and trap debris

  10. Sinuses -warm & moisten air -give *resonance to voice *richness, significance

  11. Pharynx AKA the throat • Holds tonsils, adenoids • Receives air & food from mouth • Three divisions * naso_____________ * oro ______________ * laryngo ___________

  12. Larynx AKA “Voice Box” *Contains vocal cords *Produces sound for speech

  13. One of the nine cartilage rings that make up the larynx. AKA: the __________ cartilage

  14. Epiglottis Prevents food from entering the trachea during swallowing glottis

  15. Trachea, Bronchial Tree & Alveoli AKA Windpipe * Carries air between pharynx & bronchi ************* * Right & Left Bronchi branch off trachea to take air to lungs *************** * Bronchioles carry air from bronchi to alveoli Trachea Bronchioles

  16. Alveoli *Site of cellular respiration i.e. O2 & CO2 are exchanged here *Occur in grape like clusters

  17. Lungs *Hold and support structures necessary for respiration * R has 3 lobes(divisions) * L has 2 lobes

  18. Pleura *Multilayered membrane surrounding the lung *Rich & nerve blood supply *Protects & prevents friction

  19. Diaphragm • Muscle that separated thoracic cavity from abdominal cavity • Contraction & relaxation causes respiration
