  • Respiritary system: INHALE
    • 1: Diofram: when we breath in, it contracts and flatterns, creating a bigger space.
      • involuntary muscle
      • 9L of air moves in and out of lungs
    • 2: Broncus: air passes through the Traccia and one of the Broncus into smaller Bronci
    • 3: Alvioli: it then arrives at lots of tiny sacs called alvioli
      • alvioli are surrounded by cappilaries carrying blood
    • 4: cappilaries: oxygen in the alvioli moves down a concentration ghradient into the cappillaries.
      • IMPORTANT: at the same time, carbon dioxide passes from the blood in the cappilaries into the alvioli to be exhaled
  • TIDAL VOLUME:amount of air inspired and expired in a normal breath
    • short term effect of exercise= tidal volume increases
  • VITAL CAPACITY: greates amount of air that can pass in and out of lungs in the most forceful inspiraton and experation
    • long term effect of exercise= vitral capacity increases
  • OXYGEN DEBT: amount of oxygen used in recovery to payback oxygen after anaerobic respiration
  • GASEOUS EXCHANGE: where oxygen and carbon dioxide are exchanged
