Respiratory system Flashcards
Upper respiratory tract
Nose, nasal cavity, paranasal sinuses, oral cavity, pharynx, glottis, larynx
Lower respiratory tract
Trachea, bronchus, bronchioles, aleoli
How many lobes on the right lung?
3
How many lobes on the left lung?
2
Pleura
Membrane around the lungs
Pleural fluid
Fluid in between the lungs and pleura
Pharynx
Pathway at the beginning of the back of the throat, before the glottis
Epiglottis
Flap that covers the opening of the glottis during swallowing so food doesn’t enter the lungs
Glottis
Airway through the vocal chords
Trachea
Beginning of the lower respiratory tract; above the bronchi; the windpipe
Larynx
Voice box
Alveoli
Air sacs or pouches of the lungs surrounded by capilaries that exchange gas
Bronchioles
Microscopic tubes leading to alveoli
What part of the brain senses CO2 and pH?
Medulla oblongata and pons
Bronchi
Airway branches leading to the left and right lungs
Tidal volume
Air you move through your lungs each time you inhale and exhale while you’re at rest. around 500 milliliters (mL)
Total lung capacity
maximum volume of air the lungs can hold. Measured by assessing the total amount of air in the lungs after taking the deepest breath possible
Residual volume
The volume of air remaining in the lungs after maximum forceful expiration.
Vital capacity
The total amount of air exhaled after maximal inhalation.
Total lung capacity
the volume of air in the lungs upon the maximum effort of inspiration
Emphysema
a lung disease that results from damage to the walls of the alveoli in your lungs
Diffusion
The state of being spread out or transmitted especially by contact
Lung compliance
Change in volume in lungs for a change in transpulmonary or transmural pressure.
Conductive Zone
brings inhaled air
