respiratory Flashcards
what does the respiratory supply the blood with?
Respiratory system supplies oxygen to the blood and removes waste products, primarily carbon dioxide from the blood
air moves to the lungs via the
trachae
air passageway (all)
nose/mouth –> nasopharnx –> larynx ==>trachae –> main brochi –> brochioles –> alveolar ducts–> alveolar sacs
Bronchioles are segmented into smaller passageways called
the alveolar ducts
Alveolar duct is divided and leads into three or more
alveolar sacs
“the pulmonary tree”
the entire respiratory passageway from bronchi to alveolar sacs is often referred to as
Each alveolar sac contains more than 10
alveoli
are a fine, semipermeable membrane that separates the alveolus from the capillary network
Alveoli
Across this membrane what is transported and exchanged for carbon dioxide?
oxygen
Carbon dioxide is exhaled into the air after traveling upward through the
pulmonary tree
innervation of breathing
mostly involuntary
ANS controls breathing
what happens to inspiration with anxiety and increased activity?
the sympathetic nervous system will automatically increase the depth and rate of inspiration
what component of breathing allows us control?
volitional
when is rate and depth of breathing changed?
when receptors within and outside the lungs are stimulated
what brain areas adjust the response to input from receptors in the lungs, aorta, and carotid artery?
The pons and medulla adjust their response to input from the receptors in the lungs, aorta and carotid artery
