- Respiratory system
- Responses
- Increased rate and depth of breathing
- Increased gas exchange
- Increased ventilation rate
- Short-term change as a result of exercise
- Adaptations
- Alveoli more efficient- more capillaries and more elastic
- Musculature of torso= stronger and more efficient
- Lung volume increases- greater volume of air breathed out
- Long-term change as a result of exercise
- Slightly larger lung volume
- Faster recovery, better O2 recovery, better lactic acid removal, less DOMS
- More air breathed per minute
- Bette pulmonary blood network- better blood flow
- Oxyaemoglobin curve
- Gaseous exchange more efficient= more O2 to muscles
- Shifts down and to the right during exercise
- Bohrs shift
- Gas transport
- Diffiusion
- Movement of molecule from a region of high to low concentration along a gradient
- O2 diffuses from alveoli wall to red blood cells- haemoglobin
- CO2 works in other way to O2
- Breath air through nose to- moisten air, filter air, warm air
- Diffiusion
- Inspiration (breathing in
- external intercostal muscles and diaphragm contract
- internal intercostal muscles relax
- Increased volume of thorax
- Expiration
- External intercostal muscles and diaphragm relax
- Internal intercostal muscles contract
- Decreased volume of thorax
- Air forced out more rapidly
- Responses
