Effects of Exercise on the Respiratory System

Which of the following describes the main function of the alveoli?

• Storing oxygen for later use.
• Facilitating gas exchange in the lungs.
• Providing structural support to the lungs.
• Filtering dust and particles from the air.

What are the smallest blood vessels that help transport blood carrying O2 and CO2?

• Capillaries
• Alveoli

• Bronchi

• Arteries

Identify the trachea

Identify the Bronchi

Which of the following is not a short term effect of exercise on the respiratory system?

• Increase in oxygen supply to the muscles

• Increase in cardiac output

• Shorter period before aerobic energy system becomes dominant

• Decrease in breathing rate

Which of the following changes occurs in the respiratory system during vigorous exercise?

• Decrease in tidal volume

• Decrease in oxygen uptake

• Increase in breathing rate

• Decrease in carbon dioxide production

Which structure in the respiratory system is responsible for warming and humidifying the air we breathe?

• Nasal cavity

• Trachea

• Bronchioles

• Alveoli

Which of the following is a long-term adaptation of the respiratory system to regular aerobic exercise?

• Decrease in lung capacity

• Reduced oxygen uptake

• Increase in the number of alveoli

• Improved efficiency of gas exchange

An increase in aerobic capacity means that....

• Your ability to breath increases, more oxygen inspired

• Your heart beats faster

• Your Lungs beat faster

• Your Cardiac output increases
