Question 10

Tidal volume graph

Answer 10

Steady increase

Plateu - breathing requires too much muscular effort

Question 11

Breathing rate graph

Answer 11

Directly proportional

Question 12

IC rest

Answer 12

Intercostal + phrenic nerve

Mechanics of breathing

Question 13

EC rest

Answer 13

Inactive

Question 14

IC exercise

Answer 14

Chemo - blood acidity and c02
Proprio - muscle activity
Thermo - temperature
Increased stimulation
Sternomastecloid + pectoralis minor

Question 15

EC exercise

Answer 15

Barro - lung inflamation

Internal intercostal and rectus abdominus

Question 16

02 dissociation curve

Answer 16

Shifts to right in exercise
Higher conc of pc02
Lower conc of p02
Increases diffusion gradient
Haem has lower affinity
Temp increase
Blood acidity increase
