Full Test Respirstoth Flashcards
What are the organs forming the respiratory passageway from the nasal cavity to the alveoli of the lungs?
- Nasal cavity > pharynx > trachea > bronchus > alveoli.
Nasal cavity function
warm, moisturize, and filter air entering the body before it reaches the lungs.
• Pharynx function
process swallowing, serves as a pathway for move me to of food, conducting zone, conducts air to lungs.
• Trachea function
windpipe, hollow and wide, connects larynx to bronchi, provides air flow to and from lungs.
• Bronchus function
extensions of trachea that shuttle air to and from lungs.
Highways for gas exchange
conducting zone consists of…
nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
What are some protective mechanisms of the respiratory system?
nose hairs, moist mucus lining; tonsils; coughing, cilia and sneezing
Nasal hairs
Filter foreign particles
Mucus
Traps foreign particles
Cilia
Sweeps mucus to throat
Alveolar macrophages
seek out and destroy threats on alveolar surface
Pulmonary ventilation
Air moving into and out of lungs
Inspiration
Air entering lungs
Expiration
Air leaving lungs
External respiration.
gas exchange between body exterior and blood
Internal respiration
gas exchange between blood and cells
cellular respiration
use of oxygen and CO2 by tissue cells.
What are physical factors that influence respiratory rate?
talking, coughing exercising (some overlap with non respiratory air movements;
other non-neural factors: Volition, Emotional Factors, Chemical Factors)
What are some symptoms of respiratory disease
shortness of breath, coughing w mucus, chest pain, wheezing: symptoms.
Causes of respiratory diseases
allergies, pollution, chronic illnesses or infections, visiting places w these diseases or visiting contagious ppl with them, smoking, drugs, alcohol, genetics, age.
Why are blood vessels found in alveolar tissue
That is where gas exchange occurs. Needs to b blood vessels surrounding tissue to receive and release oxygen
What’s found in the center of bronchus
Air
What is passing thru center of esophagus
Large food clump
Where is digestion completed
Small intensine
What is the purpose of the hyaline cartilage in the tracea
Helps give form and flexibility
As depth increases for a diver..,
Lung volume decrease and po2 and no2 increase
Which is not an example of an infectious disease
A. COPD
B. Pneumonia
c. Tuberculosis
D. Seasonal flu
A
In the us more men are treated w. COPD
T or F
False
What is the primary aid of decompression sickness
Breathing 100% oxygen at atmospheric pressure
What causes shortness of breath
Bronchi tubes receive air from the trachea to bring to the lungs. If the trachea becomes inflamed, there is restricted blood flow in the bronchi.
Aspect of pneumonia causing cyanosis: blue color
Lungs filled w fluid, not getting enough oxygen
What is the Glottis
Consists of vocal chords, in larynx. And slit opening between them
What is the opening to the windpipe
Glottis
What is the glottis responsible for
Voice type and sound production
What moves upward during swallowing
Glottis
Epiglottis?
Covering to the opening of the windpipe, border of glottis
Epiglottis responsible for…
Preventing food entering larynx
Difference between left and right lungs
Right lung: more concave, 2 bronchi, loves separated w horizontal fissures
Left lung: single bronchus, has an oblique fissure, lighter, smaller because of space taken up by heart.
What happens during exercise?.
Heart rate increases
Muscle cells respire more
Rate and depth of breathing increases
Auscultation
Listening to internal sounds of body.
Purpose of using auscultation
Examines circulatory system and respiratory system, and bowel sounds
