Respiratory System
the body system that functions to get oxygen from he environment and remove carbon dioxide and waste products from your body
Cellular Respiration
uses oxygen in chemical reactions that release energy
what is the function of the respiratory system?
gas exchange
the trachea leads to the...
bronchi
the space at the back of the mouth that leads either to the airway or the esophagus is the...
pharnx
oxygen from the air enters the blood stream at what location?
alveoli
Hyaline cartilage has what primary function?
support the trachea
when the diaphragm contracts, ______ occurs
inhalation
what divides the left and right side of the nasal cavity?
septums
apnea
temporary cessation of breathing (one or more skipped breaths)
dyspnea
labored (gasping) breathing (shortness of breath)
eupnea
normal, relaxed, quiet breathing
expiratory reserve volume
amount of air that can be exhaled during forced breathing
hyperpnea
increased rate and depth of breathing in response to exercise or pain
hyperventilation
reduced pulmonary ventilation in excess of metabolic demand
hypoventilation
reduced pulmonary ventilation
inspiratory reserve volume
amount of air that be inhaled during forced breating
orthopnea
dyspnea (labored, gasping breathing, shortness of breath) that occurs when a person is laying down
residual volume
amount of air remaining in the lungs after a forced exhalation
respiratory arrest
pernament cessation of breathing
tachypnea
accelerated respiration
tidal volume
amount of air inhaled or exhaled with each breath under resting conditions
total lung capacity
total volume of air that the lungs can hold
vital capacity
maximum amount of air that can expired after taking the deepest breath possible
asthma
allergens trigger the release of hisstamines and other inflammatory chemicals that cause intense bronchoconstriction
COPD
long term obstruction of airflow and a substantial reduction in pulmonary ventilation
emphysema
alveolar walls break down and the surface area of the lungs is reduced
pneumonia
lower respiratory infection that causes fluid build up in the lungs
sleep apnea
cessation of breathing for 10 seconds or longer during sleep
what is meant by the phrase "gas exchange"?
addition of oxygen to the blood and the removal of carbon dioxide
where does gas exchange take place?
alveoli
what is the process by which oxygen moves from the alveoli into the blood?
diffusion
how is oxygen carried in the blood?
haemoglobin in the red blood cells
list the structures that passes in order on its way from the nose to the alveoli
nasal cavitiy, trachea, larynx, pharynx, bronchioles, and bronchi.
what is the function mocous and cilia lining the respiratory system?
trap dust particles
how do movements of the ribs and diaphragm bring about inspiration?
the diaphragm flattens and the ribs move up and out

oxygen
