Respiratory System structure and function Questions and Answers with verified solutions

Respiratory System structure and function Questions and Answers with verified solutions Alveolar ducts - ANS- Function: connect the respiratory bronchioles to alveolar sacs. Tiny end ducts of the branching airways that fill the lungs. Alveoli - ANS- Function: Gas exchange of oxygen and carbon dioxide takes place here. Arytenoid cartilage - ANS- Function: Anchor the vocal folds (true vocal cords). Bronchioles - ANS- Function: Passageways by which air passes through the nose or mouth to the aveoli (air sacs) of the lungs. Corniculate cartilage - ANS- Function: Form part of the posterior wall of the larynx. Cricoid cartilage - ANS- Function: Attaches the larynx to the trachea via the cricotracheal ligament. Cuneiform cartilage - ANS- Function: Form the lateral aspect of the laryngeal wall. Epiglottis - ANS- Function: "Guardian of the airways." forms a lid over the larynx during swallowing. External nose - ANS- Function: The nostrils provide an entrance for air into the respiratory system. Glottis - ANS- Function: Plays a role in the Valsalva maneuver Laryngopharynx - ANS- Function: Provides for the passage of air and swallowed food. larynx - ANS- Function: Air passageway; Prevents food from entering the lower respiratory tract. Responsible for voice production. Nasal cavity - ANS- Function: Functions to filter, warm, and moisten incoming air; resonance chambers for voice production. Nasal septum - ANS- Function: Divides the nasal cavity into L and R sides. Nasal vestibule - ANS- Function: Filters course particles from the air. Nasopharynx - ANS- Function: Provides for the passage of air from the nasal cavity. Tonsils in this region provide protection against pathogens. Oropharynx - ANS- Function: Provides for the passage of air and swallowed food. Tonsils provide protection against pathogens. Paranasal sinuses - ANS- Function: Act as resonance chambers for speech; warm and moisten incoming air. Parietal Pleura - ANS- Covers the diaphragm and lines inner walls of chest. Produces pleural fluid (gliding) Primary bronchi - ANS- Function: Conducts air into the lungs Superior, middle, and inferior nasal conchae - ANS- Function: Increase the surface area of the mucosa, which enhances air turbulence and aids in trapping large particles in the mucus.
