awan
Brings air into the body
Nasal hairs in nostrils trap dust
Warms & moistens air
Glands that produce sticky mucus line the nasal cavity traps dust, pollen,
and other materials that were not trapped by nasal hairs
cilia sweep mucus and trapped material to the back of the throat where it can be swallowed
Tube-like passageway used by food, liquid, and air
At the lower end of the pharynx is a flap of tissue called the epiglottis covers the
trachea during swallowing so that food does not enter the lungs
“Voice box” The airway to
which two pairs of horizontal folds of tissue, called vocal cords, are attached
Air-conducting tube
Connects the larynx with the bronchi
Lined with mucous membranes and cilia
Contains strong cartilage rings
Two short tubes that branch off the lower end of the trachea
Carry air into the lungs.
Singular - bronchus
Tiny branches of air tubes in the lungs
Connect bronchi to alveoli
Tiny, thin-walled, grapelike clusters at the end of each bronchiole
Surrounded by capillaries
Where carbon dioxide and oxygen exchange take place
Singular - alveolus
Membrane lining the lungs and chest cavity
Muscle wall between the chest and the abdomen that the body uses for breathing
Cellular respiration requires glucose and oxygen to release energy to the body
C6H12O6 + 6O2 6CO2 + 6 H2O + Energy Oxygen is provided by the respiratory
system Glucose is provided by the digestive system (glucose is made during photosynthesis)
Human Respiratory Disorders
An inflammation of mucus membrane in bronchi.The symptom include cough followed by fever
and pain in chest
A lung infection caused byMycobacterium tuberculosis
An inflammation of the tonsils caused by bacteria
An infection caused by bacteriaCorynebacterium diphteriae. It can cause heart complication followed by fever and sometimes
can cause paralysis
A respiratory illness caused by the disturbance of respiratory muscles work. It can be caused by
allergic or physical pressure. Signed by difficulty in breathing that is shown by shortness of breath
A respiratory illness caused by swollen lung that leads to shortness breath
An inflammation of the mucus membrane of the nose
