BTEC Sport - Responses & Adaptations Respiratory System

What stimulates faster and deeper breathing during exercise?

• Increased water concentration in the blood

• Increased nitrogen concentration in the blood

• Increased carbon dioxide concentration in the blood

• Increased oxygen concentration in the blood

What allows better delivery of oxygen and removal of carbon dioxide to and from working muscles?

• Increased blood pH

• Increased blood viscosity

• Efficient gaseous exchange at the alveoli

• Increased heart rate

What will increase the efficiency breathing after a period of training?

• Increased bone density

• Increased strength of diaphragm and intercostal muscles

• Increased joint flexibility

• Increased muscle mass

What is the main factor that increases the depth and rate of breathing during exercise?

• Increased water concentration in the blood

• Increased nitrogen concentration in the blood

• Increased carbon dioxide concentration in the blood

• Increased oxygen concentration in the blood

What is the maximum increase in tidal volume from the resting state during exercise?

• 6 times

• 7 times

• 4 times

• 2 times

What is the main adaptation of the respiratory system to exercise that allows for a greater expansion of the chest cavity?

• Increased heart rate

• Increased alveoli density

• Increased blood volume

• Increased strength of diaphragm and intercostal muscles

What specific adaptation of the respiratory system allows athletes to train harder and longer?

• Increased lung capacity

• Efficient gaseous exchange at the alveoli

• Increased blood viscosity

• Increased blood pH

What is the small increase in breathing rate at the onset of exercise known as?

• Expiratory reserve

• Anticipatory rise

• Residual volume

• Inspiratory reserve

What is the main factor that stimulates faster and deeper breathing during exercise?

• Increased nitrogen concentration in the blood

• Increased acidity of the blood

• Increased oxygen concentration in the blood

• Increased water concentration in the blood

Response of the respiratory system to exercise is increased breathing rate. This is to increase the amount of what going to the working muscles?
