Respiratory System and Disorders Flashcards
(42 cards)
Function of respiratory system?
Entry of oxygen
Elimination of Carbon dioxide
Maintains pH balance within body
What’s in the upper respiratory tract?
Nose, Nasal cavity, Pharynx and Larynx
What’s in the lower respiratory tract?
Trachea, Bronchi, Bronchioles, Alveoli
Pharynx
Throat
Larynx
Voice box
Trachea
Windpipe
Lined with cilla
Bronchi
In lung
What do bronchi divide into?
Bronchioles then Alveoli
What are Alveoli?
One cell thick air sack
gas exchange take place
What is the diaphragm?
Dome shaped muscle.
Between chest and abdominal cavity.
Helps with breathing ( goes up and down when breathing in and out)
Pleura
2 layered sac covering lungs
Fluid reduces friction
How does fitness affect the respiratory rate?
Increasing fitness = Decreased RR
How does age affect the respiratory rate?
Increase in age = decrease in RR
How does OBESITY affect the respiratory rate?
Increases RR
How does SMOKING affect the respiratory rate?
Increase RR
What are some age related changes to the Respiratory system?
Weakened muscles
Reduce in lung elasticity
Decreased lung capacity
Increased rigidity of rib cage
How does the body maintain ph balance?
Exhale carbon dioxide.
Anaphylactic shock
Severe allergic reaction.
Can be life threatening
Needs epipen.
Apnea
Absence of breathing
Dyspnea
Difficulty breathing
Orthopnea
SOB when lying flat or supine.
Hyperventilation
Rapid deep breathing
Due to panic attack, infection, or another medical issue
Hypoventilation
Shallow breathing
Bronchitis
Inflammation of the bronchi
Acute or chronic
Caused by infection viral or bacteria
