respiratory

• OXYGEN- required for the body cell to synthesize chemical energy molecule
• Carbon Dioxide- is a prof of ATP production and must be removed from the blood
• SEVEN(7) STRUCTURES THAT MAKE UP RESPIRATORY SYSTEM:

  • EXTERNAL NOSE
  • NASAL CAVITY
  • PHARYNX
  • LARYNX
  • TRACHEA
  • BRONCHI
  • LUNGS
• RESPIRATION - what we call breathing.
• External nose- encloses the chamber for air inspiration. 
• Nasal cavity. is a cleaning, warming, and humidifying chamber for inspired air.
• Pharynx- is commonly called the throat. It serves as a shared passageway for food and air.
• Larynx- is frequently called the voice box. Its rigid structure helps keep the airway constantly open, or patent.
• Trachea-is commonly known as the windpipe. It

  serves as an air-cleaning tube to funnel inspired air to each lung.
• Bronchi- are tubes that direct air into the lungs.
• Lungs- is a labyrinth of air tubes and a complex network of air sacs, called alveoli, and capillaries. '
• TWO 2 MAJOR TYPES OF RESPIRATION WITHIN THE BODY

  • EXTERNAL RESPIRATION
  • INTERNAL RESPIRATION
• EXTERNAL RESPIRATION- movem of gases between the lungs and at the blood
• INTERNAL RESPIRATION- movement of gasses between the blood and body cells
