Question | Answer |
Tidal volume | Amount of air inhaled or exhaled with each breath under resting conditions ~ 500 ml |
IRV – inspiratory Reserve Volume | Amount of air that can be forcefully inhaled after a normal tidal volume inhalation ~ 3100 mL. |
amount of air that can be forcefully exhaled after a normal tidal volume exhalation ~ 1200 ml | |
Vital capacity | Maximum amount of air that can be exhaled after a maximal inhalation ~ 4800 ml |
Residual volume | the amount of air remaining in the lungs at the end of a maximum expiration |
FEV1 | Force expiratory volume in volume looks at percentage of the vital capacity that is exhaled ruing specific time intervals of FVC test, specifically the first second. |
FEV1 | amount of air expired during one second |
Where in the brain is the respiratory center inspiratory center located? | medulla |
Under normal conditions, what acts as the stimulus for inspiration? | CO2 |
Define tidal volume: | what we breathe in & out normally (at rest) |
Does hyperventilation cause acidosis or alkalosis? | alkalosis |
Does the addition of surfactant increase or decrease air flow? | increase |
Name the large cartilage of the larynx that is sometimes referred to as the Adam's apple. | thyroid cartilage |
Name the opening into the trachea which is guarded by the vocal folds (true vocal cords) | larynx |
why don't both lungs collapse when there is a penetration into the thoracic cavity | each lung is in its own cavity and they are separate from each other |
Why can you hold your breath longer after hyperventilation? | baseline to become acidic is father away. |
define pneumothorax | penetration into the thoracic cavity |
Two principles governing flow of air into and out of lungs | 1. changes in volume result in changes in 2. air flows from areas of higher pressure to lower pressure |
Name the two inspiratory muscles | external intercostals and diaphragm |
How many lobes does right lobe have? | three |
How many lobes does left lobe have? | two |
conducting zone structures | from nasal cavity to terminal brochioles; no gas exchange; anatomical dead space |
anatomical dead space | conducting zone structures |
physiological dead space | any air in where gas should be occuring but isn't due to physiological condition |
respiratory zone structures | from respiratory bronchioles outward. |
gas exchange occurs where in this whole path from trachea to alveoli? | respiratory zone structures |
during swallowing covere pharynx | epiglottis |
small cartilage that moves vocal cords | arytenoid cartilage |
corniculate cartilage | tips of arytenoid cartilage |
rings around the trachea | tracheal cartilages |
false vocal cords | vestibular fold |
true vocal cords | vocal fold |
large front cartilage | shield shaped |
adams apple | laryngeal prominence |
control center for respiratory activity | in medulla oblongata |
What tiggers medulla to make your breathe | H+ concentration |
Whast is the stimulus for inspiration? | levels of CO2, H+ & O2 in blood |
carbonic anhydrase formula | CO2 + H2O > H2CO3> h+ + HCO-3 or CO2 + H2O < H2CO3 <h+ + HCO-3 |
Increased inhalation. Acidic or basic | basic; goes to right |
decresed inhalation. acidic or basic | acidic. goes to left. increase h+, increased CO2. |
low pressure moves air into lung | inspiration, diagphragm contracts pulling downward, increasing the volume of the lung, which decreases pressue |
higher pressure pushes air out of the lung | expiration - diaphragm, decreasing the volume, which increase the pressure |
tidal volume | volume of air inspired/expired for each breath |
residual volume | left over air after forceful expiration |
