  1. Respiratory System

  2. Which Lung is Larger? • Right • Left

  3. Which Structure separates the external nares? • Conchae • Septum • Mucous Membranes • Sinuses

  4. Men have deeper voices due to… • Increase Air resistance in the nasal conchae • Denser Cartilage around the Larynx • Stronger musculature • All of the Above

  5. The “Throat” is also known as… • Larynx • Pharynx • Esophagus • Trachea

  6. The Primary function of the Nasal Cavity is to _____ air • Purify • Warm • Humidify • All of the Above • A and B only

  7. The structure which determines the direction of food or air flow is the… • Larynx • Pharynx • Epiglottis • Uvula

  8. The primary function of the “C” ring cartilage of the Trachea is to… • Decrease Air Resistance • Prevent the Trachea from collapsing • Swallowing • Purification

  9. The membrane which surrounds the Lungs is the… • Peritoneum • Pericardium • Pleural Sac • Something else that starts with “P”

  10. Oxygen moves in which direction? • Alveoli  Blood • Blood  Alveoli • Alveoli  Pleural Space • Blood  Trachea

  11. The only site of gaseous exchange occurs at the… • Alveoli • Bronchioles • Trachea • All of the above

  12. Which form of respiration is characterized by the following?-Pressure Increases- Volume Decreases- Diaphragm moves Inferiorly- Rib Cage contracts • Inspiration • Expiration • Neither

  13. Oxygen and Carbon Dioxide Exchange are characterized by… • Simple Diffusion • Facilitated Diffusion • Active Transport • All of the Above • A and C only

  14. The amount of air a person can exhale beyond normal respiration is known as • ERV • IRV • RV • FRC

  15. Total Lung Capacity is the summation of… • IRV – ERV – RV • IRV – FRC – RV • IRV – ERV –RV –TV • TV – IRV – ERV - FRC

  16. Which lung capacity is greater in terms of milliliters? • ERV • TV • IRV • RV

  17. This is an image of… • Trachea • Epiglottis • Larynx • Esophagus

  18. This image represents… • Trachea • Larynx • Epiglottis • Esophagus
