Respiration Flashcards
Forced Vibration with a tuning fork?
2nd tuning fork is tuned to the resonant frequency of the sound pressure wave.
How is an acoustic resonator made?
when the air inside a partially or completely enclosed container is set into vibration
What are the 6 parts of breathing?
Inhalation
Inspiration
Exhalation
Expiration
Gas exchange (O2 and CO2)
Diffusion
Boyle’s law:
If the volume of a gas is increased, given a constant temperature, the pressure will _______.
Decrease
Boyle’s law:
If the volume of a gas is decreased, given a constant
temperature, the pressure will _______.
Increase.
True/false:
We force air into our lungs when we inhale.
False!
We expand the volume of our lungs.
Relating to atmospheric pressure (Patmos), is the pressure negative or positive during inhalation?
Negative
During exhalation, is the pressure within the lungs negative or positive?
Positive. (causes air to flow outside)
Other name and function of C1?
Atlas, allows head to move for the ‘yes’ nod.
Other name and function of C2?
Axis, allows head to move for the ‘no’ shake.
Where do ribs attach?
superior, inferior and transverse costal facets
Where does diaphragm attach?
Lumbar vertebrae
2 bones of the pectoral girdle?
scapula and clavicle.
4 bones of the pelvic girdle?
Ilium, sacrum, pubic bone, ischium
3 types of ribs?
True: 1-7, attach directly to sternum via costal cartilage
False: 8-10, chondral portion of rib joins the costal cartilage above it (common cartilage)
Floating: 11 & 12, articulate only with vertebral column
2 zones of the visceral thorax?
conducting, repiratory
What is the conducting zone?
Respiratory passageways that carry air to respiratory zone
What is the respiratory zone?
-Site of gas exchange
-Includes respiratory bronchioles, alveolar ducts, alveoli
2 components of the tracheal wall?
mucous membrane, submucosa
How many alveoli are there?
About 300 million
How many lobes in right and left lungs?
Right=3
Left= 2
Where is the pleural cavity, and what is it filled with?
Between parietal and visceral pleurae
Filled with pleural fluid
Funciton of pleural fluid?
-holds parietal and visceral pleura together, thus lungs cling to thoracic wall, and MOVE WITH IT
-lubricates, allowing lungs to slide across the thoracic wall
Where is the parietal pleura?
internal surface of thoracic cavity
