What are the structures of the lower airways? larynx (includes adam's apple/thyroid cartilage, cricothyroid membrane, cricoid cartilage), trachea, bronchi, bronchioles, alveoli Describe the anatomy of the larynx. 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. 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. What are the structures of the lungs in order of ventilation? bronchioles, and alveoli True or false: the lungs use muscles found in the lateral lobes to expand and contract? False: the lungs are hollow organs and contain no muscles. When the diaphragm contracts it expands the thoracic cavity. The pleural space has a negative pressure and the lungs expand. This results in a slightly negative pressure (compared to the atmosphere) and air rushes in. True or false: Air rushes into the lungs because of negative pressure. True, when the lungs expand, they are creating a vacuum because they are expanding the volume of the container. This increase in volume causes influx of air into the container until the pressure is equalized with the atmosphere.
