Ch 7 Respiratory System Flashcards
This forms the false vocal cords
Vestibular Folds
What controls the respiratory system?
The Brain ( medulla oblongata)
Mouth, nasal cavity, and oral cavity
Upper Airway
Larynx, trachea, bronchi, bronchioles and alveoli
Lower Air Way
Lateral walls of the nasopharynx contain three bony ridges
Conchae
How many lobes are in the right lung.
Sits higher, larger bronchi tube
3 upper, Middle, and lower
Left lung has how many lobs and what is the tiny one called?
2 / Lingula
Medication that is designed to improve lung functions
Bronchodilator ( albuterol)
Constriction of the airways passages of the lungs that accompanies muscle spasms
Bronchospasm
Ducts formed from divisions of the respiratory bronchioles in the lower airway; each duct ends in clustes know as alveoli
Alveolar ducts
tiny sacs of lung tissue in which gas exchange takes place
Alveoli
The very thin membrane consisting of only one cell layer, that lies between the alveolus and capillary, through which respiratory exchange between the alveolus and the blood vessels
Alveolocapillary membrane
Fine subdivision of the bronchi that give rise to the alveolar ducts
Bronchioles
The process by which a gas dissolves in a liquid
Diffusion
Destruction of the walls of the alveoli, which creates resistance to expiratory airflow
Emphysema
