Chapter 7 & 8 Flashcards
condition of active infection of bronchial tree
acute bronchitis
What moves air out of lungs during relaxed ehalation?
nothing - passive process
predominant symptom of acute bronchitis
a persistent cough
causative agent for common cold
large group of viruses
most effective treatment option for cold
extra rest, drinking lots of fluids, good nutrition
how does the flu vaccine work
updated every year
alveoli fill with mucus - oxygen-carbon dioxide exchange is impaired - pleural membranes become scarred & stick together
pneumonia
pneumonia contracted in a hospital called
nosocomial infection
condition involving inflammation of nasal sinuses b/c of bacteria, virus, or fungus
infections sinusitis
bacterial infection beginning in respiratory tract but may affect other tissues - slow growing and potentially life-threatening
tuberculosis
true about the relationship between HIV and tuberculosis
HIV major risk factor for TB - risk that latent TB will become active
breathing during asthma attack
inhaling is not difficult but exhaling is extremely limited
progressive, irreversible condition involves irritation to bronchi & bronchioles
Chronic bronchitis
complication develops when heart has to work hard to push blood through the pulmonary circuit
cor pulmonale
alveoli break down and fuse forming large bullae in lungs
emphysema
elastin in bronchioles and alveoli breaks down, must recruit muscular activity to exhale
COPD
How does cystic fibrosis affect respiratory function
thick sticky secretions of mucus
person with cystic fibrosis should
carefully exercise to maintain lung funtion
lung cancer metastasizes readily because
cells have easy access to circulatory & lymph systems
Percentage of calories used for respiration at rest
5%
Why no single vaccine for colds/flue
the virus mutates quickly
synonym for common cold
viral rhinitis
causative agent for pneumonia
mycoplasma
form of sinusitis most appropriate for massage
non-infectious
most common form of pneumonia - bacteria or complication of the flu
community-acquired pneumonia
