Answer: c. the physical movement of air into and out of the lungs.
Explanation:
Pulmonary ventillation is also called as breathing. This is the process which involves the inhalation or physical entry of air inside the lungs this process is called as inspiration. And the flow out of air out of the lungs is called as exhalation. The flow of air creates a pressure difference between the atmosphere and the lungs.
Answer:
<u>Cardiac output = ejection volume X heart rate
</u>
Explanation:
CARDIAC EXPENSE, is the amount of blood that the ventricles propel every minute.
<u>
Cardiac output = ejection volume X heart rate
</u>
<u />
Cardiac output is modified by changing the volume that is expelled in each beat (<em>ejection volume or systolic volume</em>), or by changing the heart rate.
<em>The heart covers a wide range of blood flow demands. Cardiac output can range from 5 to 30 L / min, depending on the activity of the organism.</em>
Answer:
apnea
Explanation:
The absence of breathing (respiration)
The appropriate cardiorespiratory endurance guideline set by the American College of Sports Medicine for the Frequency of a workout is 20-60 minutes.
All healthy adults between the ages of 17 and 65 are advised to engage in vigorous-intensity aerobic activity for at least 20 minutes three days a week, or moderate-intensity aerobic activity for at least 30 minutes five days a week, according to the American College of Sports Medicine's cardiorespiratory endurance guidelines. According to the most recent edition of physical activity guidelines for Americans, to get the maximum health advantages from physical exercise, children and adolescents aged 6 to 17 must engage in at least 60 minutes of moderate-intensity movement each day. Thus, the duration of 20-60 minutes is considered best for aerobic exercise.
