Respiratory Lab Anatomy & Physiology The List: Trachea slide: Nostrils Tracheal lumen-air Nasal cavity Hyaline cartilage Pharynx Epiglottis Lung slide: Hyoid bone Bronchioles Larnyx ‘voce box’ Alveoli Thyroid cartilage ’Adam’s apple’ Simple squamous epithelium Trachea Blood vessel Tracheal cartilages Primary bronchi Lungs diaphragm • Respiratory zone versus conducting zone • Mechanics of Inspiration versus expiration • Tidal volume versus Vital Capacity • Gas Exchange: Pulmonary versus systemic circuits • External versus Internal respiration

Respiratory Pathway Inhaled air: 1. Enters the nostrils 2. Circulates in the nasal cavity 3. Passes through the pharynx 4. Enters and passes through the larynx to the 5. Trachea 6. Then the trachea bifurcates into 7. Two primary bronchi attached to the 8. Lungs 9. The Bronchi continue to divide until 10. They dead end at the alveolus. i n o u t

Expiration

Spirographic Record and Vital Capacity Tidal volume is quiet breathing: You are doing it now! Vital Capacity is breathing during a sprint
