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
external openings to the nasal cavity; also called the nostril
External Nares
Opening into the lower airway made up of the true vocal cords and the opening between them
Glottis
Posterior opening from the nasopharynx into the pharynx
Interior Nares
Structure that separates the nasal cavity into two parts
Nasal Septum
Nasal cavity, which extends from the internal nares to the uvula
Nasopharynx
Pleural membrane that lines the pleural cavity
Parietal Pleura
Membranes of connective tissue that cover the lungs and line the inner borders of the ribs
Pleura
The cavity formed by the inner borders of the rib cage
Pleural cavity
Potential space between the visceral and parietal pleura
Pleural Space
The volume of air remaining in the respiratory passages and lungs after a forceful expiration
Residual Volume
Organs and structures associated with breathing, gas exchange, and the entrance of air into the body
respiratory System
A device used in pulmonary function testing that measures air entering and leaving the lung over a specific period of time
Spirometer
The pleural membrane that covers the lungs
Visceral Pleura
