C7) Additional factors

Question 1

Asthma

Answer 1

Bands of muscle surrounding the airway are usually relaxed
Asthma makes the bands contract & tighten- restricting movement of air in & out

Question 2

Altitude & partial pressure

Answer 2

Lower partial pressure (less oxygen in the air)
Endurance athletes
Oxygen is more spread out- oxygen diffuses slower as pressure differences reduced
Lungs become more efficient- produce more red blood cells & capillaries
Gaseous exchange & transport of oxygen to become more efficient
