Chapter 14: Respiratory System Flashcards
right lung
3 lobes
lower
internal respiration
refers to gas exchange across the respiratory membrane in the metabolizing tissues, such as the skeletal muscles.
nares
Openings in nose that lead to nasal cavity
nostril
trachea
lower
wind pipe
16-20 C shaped cartilage
Allows air to flow into lungs
Bronchi
lower
main passageway into the lungs
main limbs of trachea
bronchitis
caused by infection or pollutant
results in swelling
infection in bronchi
pneumonia
viral or bacterial
normal breathing rate
12-20 breaths per minutes
diaphragm
Large, flat muscle at the bottom of the chest cavity that helps with breathing
Alveoli
surfactant (break surface tension of water)
the site of oxygen and carbon dioxide exchange in the respiratory system
Air sacks covered by capillaries.
Surface area equivalent to a tennis court.
Air filled chambers
tiny sacs of lung tissue specialized for the movement of gases between air and blood
Vital capacity
total amount of air moving in/out of lungs
Tidal volume and inspiratory reserve and expiratory reserve
nasal cavities
ridges inside call concha.
Warms air before it hits the lungs.
lung cancer
most common cause of cancer death in US
attributed to smoking
spread easily
diptheria
grayish membrane in throat
Larynx
Upper
voice box
behind hyoid
external respiration
gas exchange across the respiratory membrane in the lungs
flu
deadliest disease in history
tidal volume
500mL
normal breathing volume
infection
bronchitis Pneumonia Tuberculosis flu strep diptheria
Residual volume
The amount of air that remains in the lungs after a forced exhalation
1200 ml
Cyctic fibrosis
viscous mucus build up in lungs
can result in lungs bleeding
disorders of the respiratory system
emphysema
cyctic fibrosis
lung cancer
Pharynx
opening between back of nose and throat
Upper
Process
ventilation, gas exchange in lungs, transport of gas, gas exchange in tissues
