Document Summary
Kine 1020 heart continued february 3. What happens during the t-wave of the ecg: atrial depolarization, ventricle depolarization, ventricle repolarization, none of the above. Under what conditions would there be a right shift in the o2 saturation curve? (saturation on y-axis, partial pressure of oxygen on x-axis: higher ph, lower temperature, lower ph. Higher temperature (during exercise: none of the above. Arterial content of oxygen at rest is 20, dropping to 18 due to the transit time of the pulmonary capillary faster (therefore picking up less oxygen) Cardiac output in elite is much higher (18*35 to find how much oxygen is being used) therefore elite athletes use much more oxygen during exercise. Lung muscle / tissue cannot be trained. However there can be changes in cardiovascular systems (breathing: can change tidal volume which increases diaphragm size, training muscles can also increase breathing frequency which helps you not tire out easily.
