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
