Final Jeopardy Pathway of Air Final Jeopardy betting screen

Final Jeopardy Nasal cavity &/or oral cavity  pharynx  larynx  trachea  bronchi  bronchioles  alveoli List the parts of the respiratory system that air travels through, in order. Final Jeopardy

$200 Nasal cavity Single Jeopardy – Category 1 #1

$400 Trachea Single Jeopardy – Category 1 #8

$600 Right bronchus Single Jeopardy – Category 1 #6

$800 Diaphragm Single Jeopardy – Category 1 #6

$1000 Bronchioles Single Jeopardy – Category 1 #10

$200 Produce sound larynx Single Jeopardy – Category 2

Direct the passage of air to each lung (into bronchioles) $400 Direct the passage of air to each lung (into bronchioles) bronchi Single Jeopardy – Category 2

Covers glottis preventing food from entering the respiratory tract $600 Covers glottis preventing food from entering the respiratory tract Epiglottis Single Jeopardy – Category 2

$800 Gas exchange (carbon dioxide into the alveoli from pulmonary capillaries & oxygen out of alveoli into pulmonary capillaries) Alveoli Single Jeopardy – Category 2

Nasal versus oral cavity $1000 Nasal – intakes, warms, filters, & moistens air Oral – intakes, warms, & moistens Nasal versus oral cavity Single Jeopardy – Category 2

Diaphragm & intercostal muscles $200 Diaphragm & intercostal muscles Muscles involved Single Jeopardy – Category 3

Part of the brain controlling breathing rate $400 Medulla oblongata Single Jeopardy – Category 3 Part of the brain controlling breathing rate

Carbon dioxide & hydrogen ion levels $600 Carbon dioxide & hydrogen ion levels What is monitored by the carotid & aortic bodies to stimulate breathing Single Jeopardy – Category 3

How exhalation is stimulated $800 Stretch receptors in alveoli signal medulla oblongata via the vagus nerve How exhalation is stimulated Single Jeopardy – Category 3

Describe process of exhalation (expiration) $1000 Medulla oblongata sends nervous impulse to diaphragm & intercostal muscles Muscles RELAX Diaphragm moves UP Intercostal muscles move DOWN & IN Thoracic cavity gets SMALLER Pressure INCREASES Air is pushed OUT Single Jeopardy – Category 3 Describe process of exhalation (expiration)

Location of internal respiration $200 Between the systemic capillaries & the interstitial (tissue) fluid Location of internal respiration Single Jeopardy – Category 4

Optimal conditions for external respiration $400 Higher pH (~7.4) Lower temperature (~37°C) Lower pressure Single Jeopardy – Category 4 Optimal conditions for external respiration

Role of bicarbonate ion $600 Carries most of the carbon dioxide Maintains blood pH by picking up excess H+ Single Jeopardy – Category 4 Role of bicarbonate ion

3 roles of hemoglobin $800 Oxyhemoglobin (HbO2) – transports oxygen Carbaminohemoglobin (HbCO2) – transports carbon dioxide Reduced hemoglobin (HHb) – buffer picking up excess H+ Single Jeopardy – Category 4 3 roles of hemoglobin

Chemical equations for internal respiration $1000 HbO2  Hb + O2 Hb + CO2  HbCO2 CO2 + H2O  H2CO3  H+ + HCO3- H+ + Hb  HHb Single Jeopardy – Category 4 Chemical equations for internal respiration

Inspiration & expiration of air $200 Breathing Single Jeopardy – Category 5 Inspiration & expiration of air

Maximum amount of air that can be moved in & out in a single breath $400 Vital capacity Maximum amount of air that can be moved in & out in a single breath Single Jeopardy – Category 5

Function of cilia & mucus $600 Mucus traps foreign material (dust, pollen, pathogens) Cilia sweep mucus with foreign material up to pharynx Single Jeopardy – Category 5 Function of cilia & mucus

Function of surfactant $800 Helps maintain alveoli’s surface tensions preventing them from collapsing Single Jeopardy – Category 5 Function of surfactant

Chemical equation for cellular respiration $1000 6O2 + C6H12O6  6H2O + 6CO2 + ATP Chemical equation for cellular respiration Single Jeopardy – Category 5
