Adaptations

Question 1

Adaptations

Answer 1

• Increased strength of the respiratory muscles
• Increased vital capacity
• Increased in gas diffusion rate

Question 2

Increased strength of the respiratory muscles

Answer 2

• Diaphragm and intercostal muscles become stronger
• More likely to contract more forcibly
  -Increases the size of the thoracic cavity so more air can be taken to the lungs

Question 3

Increased vital capacity

Answer 3

• An increase in the thoracic cavity causes vital capacity to increase

Question 4

Increased gas diffusion rate

Answer 4

• Caused by an increase in capillaries, allowing for efficient gas exchange
