    8th Grade Ch  4 Sec 1 Respiratory System 8th Grade Ch 4 Sec 1 Respiratory System Presentation Transcript

    • Ch. 4 Sec. 1 Respiratory System
    • Discover activity- How big can you blow up a balloon? Attempt Circumference 1. 2. 3. Average of 3 attempts
    • respiration (cellular respiration)
      • process where glucose & oxygen undergo complex series of chemical reactions in cells
    • respiration
    • Systems working together
    • path of air
    • Path of air
      • NOSE
      • lined w/cilia & mucus- cleans, warms & moistens air
    • 2. PHARYNX (throat)
      • 3. TRACHEA (windpipe)
      • made of cartilage
      • lined w/cilia & mucus
      • epiglottis prevents choking
      • 4. BRONCHI (bronchus)
      • direct air  lungs
    •  
      • 5. LUNGS
      • main organs of resp. system
      • bronchi divide into smaller
      • branches (bronchioles)
    •  
      • 6. ALVEOLI (alveolus)
      • ends of bronchioles
      • hollow air sacs surrounded
      • by capillaries
      • large surface area
      • gas exchange-oxygen & CO 2
      • (& water)
    •  
    • Respiratory System activities
    •  
    •  
    • The Respiratory System [05:11]
    • breathing
      • movement of air in & out lungs
    •  
    • How you breathe
      • diaphragm =
        • large, dome-shaped muscle that plays important role in breathing
      • inhale - diaphragm moves
            • rib muscles contract
      • exhale - diaphragm moves
            • rib muscles relax
      Animation of lungs breathing
    •  
    • How you speak
      • larynx ( voice box)
        • @ top of trachea
            • vocal cords
            • stretch across opening of larynx
            • air passes over vocal cords
            • vibration creates sound
    •  
    •  
    • Time to test your knowledge
    • respiration
      • process where glucose & oxygen undergo complex series of chemical reactions in cells
    • breathing
      • movement of air in & out lungs
    • Which do you inhale when you breathe: oxygen or carbon dioxide?
    • When you inhale you breathe in oxygen . When you breathe out you exhale carbon dioxide .
    • When you inhale, does your chest expand or contract?
    • When you inhale, your chest expands . The diaphragm pulls downward.
    • Are vocal cords located inside your larynx, trachea, or esophagus?
    • The vocal cords are located inside your larynx . Hi! I’m Larry!
    • What substances are exchanged in the alveoli?
      • oxygen
      • carbon dioxide
      • water
    • Make a diagram of the respiratory system. pg. 115 Label nose, pharynx, larynx, trachea, bronchus, bronchioles, alveoli, lungs & diaphragm.
