Respiratory Concept Map
Upper respiratory structures and functions
the pharynx
carries air, food and fluid down from the nose and mouth
the larynx
helps swallow safely and contains the vocal cords
nasal cavity
acting as a barrier for the immune system to keep harmful microbes from entering the body
the nose
provides air for respiration
cleans itself of foreign debris extracted from inhalations.
Disorders of the respiratory system
lung cancer
Causes include smoking, secondhand smoke and family history.
mesothelioma
occurs in the thin layer of tissue that covers the majority of your internal organs
emphysema
air sacs of the lungs are damaged and enlarged, causing breathlessness
tuberculosis
spread from person to person through tiny droplets released into the air via coughs and sneezes
cystic fibrosis
damage to the lungs, digestive system and other organs in the body.
pulmonary hypertension
type of high blood pressure that affects the arteries in the lungs and the right side of the heart
blood vessels in the lungs are narrowed, blocked or destroyed
asthma
airways narrow and swell and may produce extra mucus
Layers of the pleurae
parietal pleura
outer pleura
attached to the chest wall
attaches to the chest wall
visceral pleura
inner pleura
covers the lungs, blood vessels, nerves, and bronchi.
protect and cushion the lungs
Major functions of the respiratory system
phonation
pulmonary defense
acid-base balance
handling of bioactive materials
gas exchange
Lower respiratory structures and functions
the bronchi
two large tubes that carry air from your windpipe to your lungs
the bronchioles
involved in the conduction of air as well as gas exchange
the trachea
long tube that connects your larynx to your bronchi
carry air in and out of your lungs
the alveoli
air passes through the alveoli and into the blood and travels to the tissues throughout the body.
Compare and contrast the mechanism of inspiration and expiration
inspiration
the process of taking air into the lungs whereas
inhalation
active process where it brings air into the lung
expiration
exhalation
the process of liberating air from the lungs
passive process which is the expulsion of the air out of the lungs
Volume and Pressure relationships in thoracic cavity
the pressure in the lung will decrease
the lung increases during inspiration
Respiratory volumes and capacities
inspiratory reserve
amount of air a person can inhale forcefully after normal tidal volume
expiratory reserve
the amount of extra air above-normal volume exhaled during a forceful breath out
tidal
the amount of air that moves in or out of the lungs with each respiratory cycle
residual volumes
the amount of air that remains in a person's lungs after fully exhaling
Internal vs. external respiration
Internal respiration
process of diffusing oxygen from the blood
the interstitial fluid and into the cells
Oxygen diffuses out from the blood into tissue during internal respiration
external respiration
formal term for gas exchange
transfer of oxygen and carbon dioxide into the bloodstream through diffusion
bringing air into the lungs
