THE ULTIMATE FISDAP AIRWAY STUDY GUIDE UPDATE|A GRADED|NEW From the atmosphere, what structures does air pass through during ventilation? - ANSWER- Starts in atmosphere, then nose, nasopharyngeal space/orophargyneal space (if mouth breather), then pharynx, larynx, trachea, bronchi, bronchioles, alveoli What is the purpose of the nasal passages and nasopharynx? - ANSWER- To warm/humidify air as it passes through What is the difference between respiration and ventilation? - ANSWER- Respiration refers to the exchange of gases in the alveoli, ventilation refers to the movement of air into the lungs. Respiration is needed to provide O2 to cells and remove waste products. Also regulates pH of blood. What are the structures of the upper airway? - ANSWER- nose, mouth, tongue, jaw, pharynx and larynx What structure is considered a landmark that divides the upper airway from lower? - ANSWER- The larynx, anything above is upper. The larynx and below are lower. What are the structures of the lower airways? - ANSWER- larynx (includes adam's apple/thyroid cartilage, cricothyroid membrane, cricoid cartilage), trachea, bronchi, bronchioles, alveoli Describe the anatomy of the larynx. - ANSWER- From superior to inferior. Thyroid cartilage, cricothyroid membrane, and cricoid membrane. The thyroid cartilage and cricoid cartilage are anterior to the larynx, and the cricothyroid membrane is posterior to both structures. True or false: the lungs are completely equal in the midsaggital plane. - ANSWER- False, right lungs has 3 lobes, left lung only has 2 lobes. Together they have 5 total. Also, the right bronchi is inferior to the left bronchi
