If the game is tied after the away team earns 3 outs in the bottom of the ninth, the game goes into extra innings. Keep Learning.
Gas Exchange During Exercise. During exercise, your body needs more energy, which means your tissues consume more oxygen than they do at rest. Consuming more oxygen means you will also produce more carbon dioxide because your metabolic rate is elevated. The ratio of carbon dioxide produced per oxygen consumed also increases during exercise because a shift from fat to carbohydrate utilization takes place. At the most challenging work rates, you burn carbohydrates exclusively and produce 1.0 liter of carbon dioxide for every liter of oxygen you consume.
Best Answer: During exercise, the cells burn oxygen faster to produce more energy for the body, which creates more carbon dioxide as a waste product. This increased carbon dioxide level is detected by the brain, which signals for a higher respiration rate to provide more oxygen for the cells.During exercise, the body's need for oxygen increases dramatically and ventilation rate is increased.The depth of breathing also increases during exercise during exercise due to the anatomical dead space of the respiratory system.The anatomical dead space is the air in the nose, mouth, larynx, tracheas, bronchi and bronchioles.his increased carbon dioxide level is detected by the brain, which signals for a higher respiration rate to provide more oxygen for the cells. During exercise, the body's need for oxygen increases dramatically and ventilation rate is increased.
