The Respiratory System Questions with accurate answers, 100% Accurate. What three regions is the Pharynx divded into? - ✔✔-Nasopharynx, Oropharynx, Laryngopharynx. Where is the Pharynx located... ? - ✔✔-From the base of the skull to the level of the sixth cervical vertebra. What is the location of the Nasopharynx? - ✔✔-Lies posterior to the nasal cavity. What is the function of the Nasopharynx? - ✔✔-Strictly an air passageway. Closes during swallowing to prevent food from entering the nasal cavity. What accessory organ is in the Nasopharynx? - ✔✔-The Pharyngeal tonsils (adenoids) that lie high on the posterior wall. What are the tubes that open into the lateral walls of the Nasopharynx? - ✔✔-The Pharyngotympanic auditory tubes. What is the location of the Oropharynx? - ✔✔-Extends inferiorly from the level of the soft palate to the epiglottis. What is the function of the Oropharynx? - ✔✔-Serves as a common passageway for food and air. What accessory organs are in the Oropharynx? - ✔✔-The Palatine tonsils that lie in the lateral walls of the fauces (latin for throat), and the Lingual tonsils that covers the base of the tongue. What is the location of the Laryngpharynx? - ✔✔-Lies posterior to the upright epiglottis. What is the function of the Laryngopharynx? - ✔✔-Serves as a common passageway for food and air. What is the location of hte Larynx? - ✔✔-Attaches to the hyoid bond, continuous with the trachea posteriorly. What are the function of the Larynx? - ✔✔-To provide a patent airway, to route air and food into the proper chanels, to function in voice production. What is the Epiglottis? - ✔✔-Elastic cartilage that covers the laryngeal inlet during swallowing. What is the function of the Vocal Folds (True Vocal Cords)? - ✔✔-Folds vibrate to produce sound as air rushes up from the lungs. What is the function of the False Vocal Cords (Vestibular Fold)? - ✔✔-Have no function in sound production. What is the opening between the vocal folds? - ✔✔-The glottis. What is Speech? - ✔✔-Intermittent release of expired air while opening and closing the glottis. What is Pitch? - ✔✔-Determined by the length and tension of the vocal cords. What is Loudness? - ✔✔-Depends upon the force at which the air rushes across the vocal cords. What chambers amplify and enhance sound quality? - ✔✔-Pharynx, oral, nasal and sinus cavities. How is sound shaped into launguage? - ✔✔-By action of the pharynx, tongue, soft palate, and lips. What is the primary bronchi? - ✔✔-Trachea. What does each bronchus enter? - ✔✔-The hilum of one lung. Which bronchus is wider, shorter and more vertical? - ✔✔-Right main bronchus. What do each main bronchus branch into? - ✔✔-Lobar (secondary) bronchi. What does each lobar bronchus branch into? - ✔✔-Segmental (tertiary) bronchi. What is the diameter of a bronchiole? - ✔✔-Less than 1 mm. What is the diameter of terminal bronchioles? - ✔✔-Less than 0, are the smallest. What accounts for most of the lungs volume and are the mains ite for gas exchange? - ✔✔-300 million Alveoli. What is the function of Alveoli? - ✔✔-Provide tremendous surface area for gas exchange. What two circulations are the lungs perfused by? - ✔✔-Pulmonary and bronchial. What are Pulmonary Arteries? - ✔✔-Supply systemic venous blood to be oxygenated. What are Pulmonary Veins? - ✔✔-Carry oxygenated blood from the respiratory zones to the heart. What are Bronchial Arteries? - ✔✔-Provide system blood to the lung tissue. What do bronchial veins anastomose with? - ✔✔-Pulmonary veins. What are the two phases pulmonary ventilation consists of? - ✔✔-Inspiration and Expiration. What is Inspiration? - ✔✔-Gases flow into the lungs. What is Expiration? - ✔✔-Gases exit the lungs. What is Atmospheric Pressure? - ✔✔-Patm. Pressure exerted by the air surrounding the body. What is the Atmospheric Pressure at Sea Level? - ✔✔-760 mm Hg. What is Respiratory Pressure? - ✔✔-Relative to Patm. What is Negative Respiratory Pressure? - ✔✔-Less than Pat [Show More]
