Answer:
Sprinter hold their breath while marathon runner didn't.
Explanation:
A sprinter can use mainly anaerobic respiration during the race because a sprinters hold their breath during a race so due to lack of oxygen it takes energy from anaerobic respiration, while a marathon runner needs to use aerobic respiration because he use oxygen during their race and by using oxygen aerobic respiration is executed. So we can conclude that sprinters use anaerobic respiration while marathon runner use aerobic respiration during running.
Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.
