what portions of the respiratory system are referred to as anatomical dead space

Why? Because no gas exchange occurs except in the respiratory zone, particularly in the alveoli. What portions of the respiratory system are referred to as anatomical dead space? The space in which oxygen (O2) and carbon dioxide (CO2) gasses are not exchanged across the alveolar membrane in the respiratory tract 12. Trace a molecule of oxygen from the nostrils to the pulmonary capillaries of the lungs: Nostrils - nasal cavity -pharynx - larynx – trachea - primary bronchus - tertiary/secondary bronchi (etc.) - respiratory bronchiole - alveolar duct - alveolar sac- across alveolar/capillary wall - pulmonary blood 11.

Which more commonly traps a foreign object that has entered the respiratory passageways? Right bronchus 10. Which is longer? Left Larger in diameter? Right More horizontal? Left 9. The following questions refer to the main bronchi. Name two functions of the nasal conchae: increases the cavity's surface area and creates air turbulence to filter, warm or cool, and humidify the air 8. What is the function of the pleural fluid? Pleural fluid keeps the pleura moist and reduces friction between the membranes when you breathe 7.

Why is it important that the rings are incomplete posteriorly? The main reason why the C-shaped cartilage rings are incomplete is that they allow the trachea to narrow 6. Why is it important that the human trachea is reinforced with cartilaginous rings? The cartilage rings in the trachea reinforce the trachea walls to keep its passageway open regardless of the pressure changes that occur during breathing 5. a “lid” for the larynx: elastic - vocal cord attachment: retinoidĤ.forms the Adam’s apple: cricoid - shaped like a ring: posterior.Name the specific cartilages in the larynx that correspond to the following descriptions. Which pair are the true vocal cords (superior or Inferior)? Inferior 3. Two pairs of vocal folds are found in the larynx.
