5 Mouth & Nose Brings air into the body Nasal hairs in nostrils trap dust
6 Nasal cavity Warms & moistens air Glands that produce sticky mucus line the nasal cavitytraps dust, pollen, and other materials that were not trapped by nasal hairscilia sweep mucus and trapped material to the back of the throat where it can be swallowed
7 Pharynx Tube-like passageway used by food, liquid, and air At the lower end of the pharynx is a flap of tissue called the epiglottis
8 Larynx“Voice box”The airway to which two pairs of horizontal folds of tissue, called vocal cords, are attached
9 Trachea Air-conducting tube Connects the larynx with the bronchi Lined with mucous membranes and ciliaContains strong cartilage rings
10 Bronchi Two short tubes that branch off the lower end of the trachea Carry air into the lungs.Singular - bronchus
11 Bronchioles Tiny branches of air tubes in the lungs Connect bronchi to alveoli
12 AlveoliTiny, thin-walled, grapelike clusters at the end of each bronchioleSurrounded by capillariesWhere carbon dioxide and oxygen exchange take placeSingular - alveolus
16 DiaphragmMuscle wall between the chest and the abdomen that the body uses for breathing
17 Inhale 02, our diaphragm contacts and pulls down, rib expand, lungs Inflate Exhale CO2, diaphragm relaxes and moves up our ribs go back in, and Our lungs deflate.
18 Relationship to digestive system Cellular respiration requires glucose and oxygen to release energy to the bodyC6H12O6 + 6O2 6CO2 + 6 H2O + EnergyOxygen is provided by the respiratory systemGlucose is provided by the digestive system(glucose is made during photosynthesis)
