Tidal volume is the amount of air breathed in with each normal breath. Lung volumes are the volume of gas in the lungs at a given time during the respiratory cycle and include tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at. If a damaged lung loses surfactant, then the other lung can supply the lost surfactant. Therefore the main factors impacted in chronic adaptation to exercise are blood flow, and oxygen extraction in the tissues. 2 Most CO2 that diffuses into the systemic capillaries from, What would happen if the body allowed us to exhale all of the air out of our lungs? d. Intrapleural pressure decreases.
