Respiratory System Vanessa Gasca Sosa
Per. 2
Major functions
obtains oxygen from atmosphere & removes carbon dioxide from body cells
removes particles from incoming air
regulates temp. & water content of the air
provides vocal sounds
regulates blood pH
helps sense of smell
Upper Respiratory structure & functions
Structures: nose, para-nasal sinus, nasal cavity, pharnyx
Function: Nose provides entrance and release of air, para-nasal sinus opens nasal cavity, nasal cavity humidifies the air, and pharynx is the passageway for air and oral cavities
layers of pleurae
:
parietal pleura(outer layer)
pleural cavity
visceral pleura(inner layer)
Compare & contrast mechanisms of inspiration & expiration
Compare
:
main parts of the respiration process
oxygen & carbon dioxide are present
Contrast
:
Ins. is the intake of air into lungs, exp. is the expulsion of air our out of the lungs
Ins. is active process while exp. is passive process
Volume & pressure relationships in thoracic cavity
Increase in volume decreases the intralveolar pressure creating low pressure in the atmosphere
Respiratory volumes and capacities
:
Tidal volume(TV)
Inspiratory reserve volume (IRV)
Expiratory reserve volume (ERV)
Residual volume (RV)
Vital capacity(VC)
Inspiratory capacity (IC)
Functional residual capacity(FRC)
notes ch16B
Internal v. External respiration
Internal respiration
: gas exchange between blood & body cells
External respiration
: gas exchange between lungs & blood
Disorders of respiratory system
: asthma, chronic obstructive pulmonary disease, chronic bronchitis, emphysema, lung cancer, cystic fibrosis/bronchiectasis, pneumonia, & pleural effusion
Lower Respiratory structure & function
Structure
Larynx, trachea, bronchial tree, lungs
Function
Larynx transports air in and out of trachea. Trachea carries carries air out lungs, and bronchial tree is the mucous membrane which distributes air into lungs. Lungs bring oxygen into our bodies
