Why can prolonged stress result in cardiovascular disease? The increase in arterial PCO2 and H+ stimulates chemoreceptors resulting in a stimulation of respiratory centers in medulla. Oxygen enters into the lungs while breathing simultaneously; carbon dioxide moves out from the lungs. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. Vital capacity is the maximum amount of air that can be breathed out after breathing in as much air as possible. 6 How is the expiratory reserve volume related to tidal volume? During exercise, tidal volume increases as the depth of breathing increases and the rate of breathing increases too. To sum up: Your expiratory reserve volume is the amount of extra air above anormal breath exhaled during a forceful breath out. The inspiratory muscles include the intercostals and the diaphragm. (a) Why it is important to "warm-up" before exercise? What prevents the alveoli membranes from sticking together during exhalation? How does vital capacity of the lungs change with age? However, long term exercise where the body becomes accustomed to increased airflow and rate of breathing over time can increase the vital capacity. After reviewing the discussion of the respiratory cycle, explain why this change forcefully expels air out the nose and mouth. 1 Residual volume is one of several factors that doctors measure during pulmonary function testing to determine how .

Understand what ventilation is. During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. All rights reserved. VC is the the most volume of air that be be released from your lungs after you take the biggest breath you may physically be able to. Taking part in regular aerobic exercise has been shown to increase a persons vital capacity. The TP interval decreasing from 0.32 seconds at rest to just 0.08 seconds after exercise, a decrease of 0.24 seconds (just 25% of the resting 0.32 seconds). As PCO2 increases it combines with water to form carbonic acid. Explain how that would occur. In healthy individuals, exercise produces either a mild bronchodilatation, facilitating an increase in airflow without a significant increase in airway resistance and the work of breathing, 1 or has no effect. This experiment tested the hypothesis that there was no difference between cellular respiration before vigorous exercise and cellular respiration after vigorous exercise in terms of rate of cellular respiration. 10.
