- 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
- 1: Diofram: when we breath in, it contracts and flatterns, creating a bigger space.
- 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
